Digging Into Durham’s Eviction Problem

This is what 20 years of evictions looks like. It’s an animated heat map of Durham, the streets overlaid with undulating blobs of red and orange and yellow, like a grease stain.

Duke students in the summer research program Data+ have created a time-lapse map of the more than 200,000 evictions filed in Durham County since 2000.

Dark red areas represent eviction hotspots. These neighborhoods are where families cook their favorite meals, where children do their homework, where people celebrate holidays. They’re also where many people live one crisis away from losing their neighbors, or becoming homeless themselves.

Duke junior Samantha Miezio points to a single census tract along NC 55 where, in the wake of an apartment building sale, more than 100 households received an eviction notice in that spot in one month alone. It “just speaks to the severity of the issue,” Miezio said.

Miezio was part of a team that spent 10 weeks this summer mapping and analyzing evictions data from the Durham County Sheriff’s Office, thanks to an effort by DataWorks NC to compile such data and make it more accessible.

The findings are stark.

Every hour in Durham, at least one renter is threatened with losing their home. About 1,000 eviction cases were filed a month against tenants between 2010 and 2017. That’s roughly one for every 280 residents in Durham, where evictions per capita is one of the highest in the state and double the national average.

The data tell us that while Durham’s evictions crisis has actually improved from where it was a few years ago, stubborn hotspots persist, said team member Ellis Ackerman, a math major at North Carolina State University.

When the students looked at the data month by month, a few things stood out. For one, winter evictions are common. While some countries such as France and Austria ban winter evictions to keep from pushing people onto the street in the cold, in Durham, “January is the worst month by far,” said team member Rodrigo Araujo, a junior majoring in computer science. “In the winter months utility bills are higher; they’re struggling to pay for that.”

Rodrigo Araujo (Computer Science, 2021) talks about the Durham evictions project.

The team also investigated the relationship between evictions and rents from 2012 to 2014 to see how much they move in tandem with each other. Their initial results using two years’ worth of rent data showed that when rents went up, evictions weren’t too far behind.

“Rents increased, and then two months later, evictions increased,” Miezio said.

But the impacts of rising rents weren’t felt evenly. Neighborhoods with more residents of color were significantly affected while renters in white neighborhoods were not. “This crisis is disproportionately affecting those who are already at a disadvantage from historical inequalities,” Miezio said.

A person can be evicted for a number of reasons, but most evictions happen because people get behind on their rent. The standard guideline is no more than 30% of your monthly income before taxes should go to housing and keeping the lights on.

But in Durham, where 47% of households rent rather than own a home, only half of renters meet that goal. As of 2019 an estimated 28,917 households are living in rentals they can’t afford.

The reason is incomes haven’t kept pace with rents, especially for low-wage workers such as waiters, cooks, or home health aides.

Durham’s median rents rose from $798 in 2010 to $925 in 2016. That’s out of reach for many area families. A minimum wage worker in Durham earning $7.25/hour would need to work a staggering 112 hours a week — the equivalent of nearly three full-time jobs — to afford a modest two-bedroom unit in 2019 at fair market rent, according to a report by the National Low Income Housing Coalition.

Spending a sizable chunk of your income on housing means having less left over for food, child care, transportation, savings, and other basic necessities. One unexpected expense or emergency — maybe the kid gets sick or the car needs repairs, or there’s a cut back on hours at work — can mean tenants have a harder time making the rent.

“Evictions are traumatic life experiences for the tenants,” and can have ripple effects for years, Miezio said.

Tenants may have only a few days to pay what’s due or find a new place and move out. The Sheriff may come with movers and pile a person’s belonging on the curb, or move them to a storage facility at the tenant’s expense.

A forced move can also mean children must change schools in the middle of the school year.

Benefits may go to the wrong address. Families are uprooted from their social support networks of friends and neighbors.

Not every case filed ends with the tenant actually getting forced out, “but those filings can still potentially inhibit their ability to find future housing,” Miezio said. Not to mention the cost and hassle of appearing in court and paying fines and court fees.

Multiple groups are working to help Durham residents avoid eviction and stay in their homes. In a partnership between Duke Law and Legal Aid of North Carolina, the Civil Justice Clinic’s 2-year-old Eviction Diversion Program provides free legal assistance to people who are facing eviction.

“The majority of people who have an eviction filed against them don’t have access to an attorney,” Miezio said.

In a cost-benefit analysis, the team’s models suggest that “with a pretty small increase in funding to reduce evictions, on the order of $100,000 to $150,000, Durham could be saving millions of dollars” in the form of reduced shelter costs, hospital costs, plus savings on mental health services other social services, Ackerman said.

Ellis Ackerman, a senior math major from NC State University, talks about the Durham evictions research project.

Moving forward, they’re launching a website in order to share their findings. “I’ve learned HTML and CSS this summer,” said Miezio, who is pursuing an individualized degree program in urban studies. “That’s one of the things I love about Data+. I’m getting paid to learn.”

Miezio plans to continue the project this fall through an independent study course focused on policy solutions to evictions, such as universal right to counsel.

“Housing access and stability are important to Durham,” said Duke’s vice president for Durham affairs Stelfanie Williams. “Applied research projects such as this, reflecting a partnership between the university and community, are opportunities for students to ‘learn by doing’ and to collaborate with community leaders on problem-solving.”

Vulci 3000: Technology in Archaeology

This is Anna’s second post from a dig site in Italy this summer. Read the first one here.

Duke PhD Candidate Antonio LoPiano on Site

Once home to Etruscan and Roman cities, the ruins found at Vulci date to earlier than the 8th century B.C.E.

As archaeologists dig up the remains of these ancient civilizations, they are better able to understand how humans from the past lived their daily lives. The problem is, they can only excavate each site once.

No matter how careful the diggers are, artifacts and pieces of history can be destroyed in the process. Furthermore, excavations take a large amount of time, money and strenuous labor to complete. As a result, it’s important to carefully choose the location.

Map of the Vulci Landscape Created Using GIS Technology

In response to these challenges Dr. Maurizio Forte decided to supplement the excavation of ancient Vulci sites by using innovative non-invasive technologies. 

Considering that it once housed entire cities, Vulci is an extremely large site. To optimize excavation time, money, and resources, Dr. Forte used technologies to predict the most important urban areas of the site. Forte and his team also used remote sensing which allowed them to interpret the site prior to digging.

Having decided where on the site to look, the team was then able to digitally recreate both the landscape as well as the excavation trench in 3D. This allowed them to preserve the site in its entirety and uncover the history that lay below. Maps of the landscape are created using Web-GIS (Geographic Information Systems). These are then combined with 3D models created using photogrammetry to develop a realistic model of the site.

Forte decided to make the excavation entirely paperless. All “paperwork”  on site is done on tablets. There is also an onsite lab that analyzes all of the archaeological discoveries and archives them into a digital inventory.

This unique combination of archaeology and technology allows Forte and his team to study, interpret and analyze the ancient Etruscan and Roman cities beneath the ground of the site in a way that has never been done before. He is able to create exact models of historic artifacts, chapels and even entire cities that could otherwise be lost for good.

3D Model Created Using Photogrammetry

Forte also thinks it is important to share what is uncovered with the public. One way he is doing this is through integrating the excavation with virtual reality applications.

I’m actually on site with Forte and the team now. One of my responsibilities is to take photos with the Insta360x which is compatible with the OculusGo, allowing people to experience what it’s like to be in the trench with virtual reality. The end goal is to create interactive applications that could be used by museums or individuals. 

Ultimately, this revolutionary approach to archaeology brings to light new perspectives on historical sites and utilizes innovative technology to better understand discoveries made in excavations.

Vulci 3000: A High-Tech Excavation

This summer I have the incredible opportunity to work with the Vulci 3000 Bass Connections team. The project focuses on combining archaeology and innovative technology to excavate and understand an ancient Etruscan and Roman site. Over the next several weeks I will be writing a series of articles highlighting the different parts of the excavation. This first installment recounts the history of the project and what we plan to accomplish in Vulci.

Covered in tall grasses and grazing cows it’s hard to imagine that the Vulci Archaeology Park was ever something more than a beautiful countryside. However, in reality, it was home to one of the largest, most important cities of ancient Etruria. In fact, it was one of the biggest cities in the 1st millennium BCE on the entire Italian peninsula. Buried under the ground are the incredible remains of Iron Age, Etruscan, Roman, and Medieval settlements.

Duke’s involvement with the Vulci site began in 2015 when Maurizio Forte, the William and Sue Gross Professor of Classical Studies Art, Art History, and Visual Studies visited the site. What was so unique about the site was that most of it was untouched.

One of the perils of archaeology is that any site can only be physically excavated once and it is inevitable for some parts to be damaged regardless of how careful the team is. Vulci presented a unique opportunity. Because much of the site was still undisturbed, Forte could utilize innovative technology to create digital landscapes that could be viewed in succession as the site was excavated. This would allow him and his team to revisit the site at each stage of excavation. In 2015 he applied for his first permit to begin researching the Vulci site.

In 2016 Forte created a Bass Connections project titled Digital Cities and Polysensing Environments. That summer they ventured to Italy to begin surveying the Vulci site. Because Vulci is a large site it would take too much time and money to excavate the city. Instead, Forte and his team decided to find the most important spots to excavate. They did this by combining remote sensing data and procedural modeling to analyze the various layers underground. They collected data using magnetometry and ground-penetrating radar. They also used drones to capture aerial photography of the site.

These technologies allowed the team to locate the urban areas of the site through the discovery of large buildings and streets revealed by the aerial photographs, radiometrically-calibrated orthomaps, and 3D point cloud/mesh models.

The project continued into 2017 and 2018 with a team returning to the site each summer to excavate. Within the trench were archaeologists ranging from undergrads to postdocs digging, scraping and brushing for months to discover what lay beneath the surface. As they began to uncover rooms, pottery, coins, and even a cistern, groups outside the trench continued to advanced technology to collect data and improve the understanding of the site.

Nevio Danelon Releasing a Drone

One unit focused on drone sensing to digitally create multispectral imagery as well as high-resolution elevation models. This allowed them to use soil and crop marks to better interpretation and classify the archaeological features.

By combining traditional archaeology and innovative technology the team has been able to more efficiently discover important, ancient artifacts and analyze them in order to understand the ancient Etruscan and Roman civilizations that once called Vulci their home.

Photo Taken Using the Insta360 Camera in “Planet” Mode

This year, archaeologists return to the site to continue excavation. As another layer of Vulci is uncovered, students and faculty will use technology like drones, photogrammetry, geophysical prosecutions and GIS to document and interpret the site. We will also be using a 360 camera to capture VR compatible content for the OculusGo in order to allow anybody to visit Vulci virtually.

Chronicling Migrant Deaths Along the US-Mexico Border

Science, especially social science, is rarely apolitical. Nonetheless, researchers are often hesitant to engage with the political implications of their work. Striving to protect their objective, scientific stance, they leave the discussing and at times the fighting to the politicians and legislators.

University of Michigan anthropologist Jason de León is not one of those researchers. Politics is not merely implicated in his work, but rather drives it. De León studies undocumented migration between Mexico and the United States.

University of Michigan anthropologist Jason De León directs the Undocumented Migration Project.

As director of the Undocumented Migration Project, De León studies what happens to the bodies of migrants crossing the desert to reach the U.S. using “any genre I can steal from,” he told an audience at Duke University on April 5. Using tools from archeology, forensics, photography, and ethnography, de León and his team have been providing novel insights into one of the most urgent political challenges currently facing the nation.

De León acknowledged the political reality of his work immediately by opening his talk with a quote from President Trump about building a “great wall.” However, he was quick to clarify that the problem of missing migrants is not partisan. Rather, it has a long history that he argues started with the 1993 immigration enforcement policy, “Prevention through Deterrence.” This policy’s aim was to redirect illegal immigration to the desert rather than to stop it. Politicians hoped that in the desert, where security is weak and the terrain treacherous, the natural terrain would serve as a border wall. Inherent in this policy is the assumption that migrant life is expandable.

In the wake of this policy, the human smuggling industry in northern Mexico experienced a swift influx and the number of known migrant deaths began to rise. Since the 1990s, over 600 migrant bodies have been recovered from the Sonoran Desert of Arizona where de León conducts his research. Until his team conducted the first forensic experiments on the site, people could only speculate as to what was happening to the bodies of missing loved ones hoping to make it across the border. Now, de León can offer some helpful if heartbreaking data.


De León examines the human consequences of U.S. immigration policy in his book, “The Land of Open Graves”

De León’s archeological method, “desert taphonomy,” examines both the natural and cultural processes that determine what happens to a dead body. Anthropologists studying the body’s decomposition were initially interested only in natural factors like the climate and scavenging animals. Recently, they have realized that the decomposition process is as social as it is natural, and that the beliefs and attitudes of the agents involved affect what happens to human remains. According to this definition, a federal policy that leaves dead bodies to decompose in the Arizona desert is taphonomy, and so is the constellation of social, economic, and political factors that drive people to risk their lives crossing a treacherous, scorching desert on foot.

Guided by this new approach, de León studies social indicators to trace the roots of missing bodies, such as “migrant stations” made up of personal belongings left behind by migrant groups, which he says can at times be too big to analyze. De León and his team document these remnants with the same respect they pay to any traditional archeological trail. Items that many would dismiss as trash, such as gendered items including clothes and hygiene products, can reveal much needed information about the makeup of the migrant groups crossing the desert.

De León argues that human decomposition is a form of political violence, caused by federal policies like Prevention through Deterrence. His passion for his research is clearly not driven by mere intellectual curiosity; he is driven by the immense human tragedy of migrant deaths. He regularly conducts searches for missing migrants that families reach out to him about as a desperate last measure. Even though the missing individuals are often unlikely to be found alive, de León hopes to assuage the trauma of “ambiguous loss,” wherein the lack of verification of death freezes the grief process and makes closure impossible for loved ones.

The multifaceted nature of de León’s work has allowed him to inspire change across diverse realms. He has been impactful not only in academia but also in the policy and public worlds. His book, “The Land of Open Graves,” is accessible and poetic. He has organized multiple art exhibitions that translate his research to educate and empower the public. Through the success of these installations, he has come to realize that exhibition work is “just as valuable as a journal article.”

Hearing about the lives that de León has touched suggests that perhaps, all researchers should be unafraid to step outside of their labs to not only acknowledge but embrace the complex and critical political implications of their work.

A How-To Guide for Climate-Proof Cities

Roughly 400 miles separate Memphis and New Orleans. Interstate 55 connects the two cities, snaking south parallel to the Mississippi River. The drive is dull. There are few cars. The trees are endless.

South of the Louisiana border, the land turns flat, low, and wet. The air grows warmer, and heavy with moisture. I-55 cuts through the center of Maurepas Swamp, a 100,000-plus acre tract of protected wetlands. Groves of gumball and oak are rare here—instead, thin swamps of bald cypress and tupelo trees surround the highway on either side. At night, only their skeletal silhouettes are visible. They rise from the low water, briefly illuminated by passing headlights. Even in the dark, the trees are unmistakably dead.

Traditionally, Maurepas Swamp serves as a natural barrier against flooding that threatens New Orleans each year. Native flora soaks up the rainfall, spreading it across a network of cypress roots and cattail. But centuries of logging and canal construction have drastically altered the swamp’s ecological composition. The Mississippi levee system compounded the issue, isolating the swamp from vital sources of fresh water and nutrients. Flooded with saltwater, much of the existing cypress withered and died. Young trees, now, are few and scattered. 

Maurepas Swamp highlights the danger of even the most well-intentioned changes to the  environment. This problem is hardly unique to the wetlands. “Many of the issues that we are experiencing today were seen as solutions in the past,” says Nancy Grimm, a professor of ecology at Arizona State University. “What we want to do now is to think about the future, so that the solutions of today don’t become the problems of tomorrow.”

Grimm is the co-director of the UREx Sustainability Research Network. UREx aims to climate-proof urban municipalities without sacrificing environmental stability. To do so, UREx has partnered with several cities across the United States and Latin America. Each city hosts a workshop geared towards municipal decision makers, such as government officials,  environmental NGOS, and more. Together, these participants design different “futures” addressing their cities’ most pressing concerns. 

Phoenix, Arizona is one of the nine initial cities partnering with UREx. One of the hottest cities in the United States, Phoenix is already plagued with extreme heat and drought. By 2060, Phoenix is projected to have 132 days above 100°F—a 44 percent increase from data collected in 2010.  

UREx doesn’t dwell too much on these statistics.  “We’re bombarded constantly by dystopian narratives of tomorrow,” says Grimm, with a slight smile. “Instead, what we want to think about are ways we can envision a more positive future.”

The Phoenix workshop produced five distinct visions of what the city could look like in sixty years. Some scenarios are more ambitious than others—“The Right Kind of Green,” for example, imagines a vastly transformed city defined by urban gardens and lush vegetation. But each vision of Phoenix contains a common goal: a greener, cooler city that retains its soul. 

A visualization accompanies each scenario. In one, a family walks about a small orchard. The sky is blue, and the sun is out. But no one seems bothered by the heat. The oranges are vibrant; the trees thick, and full. It’s an idyllic future. But it’s one within grasp.

Open Communication is Key to Research in Schools

One of the things that excited me most about coming to Duke was the amount of research being done on campus, from theoretical physics to biological field work or cultural anthropology. I recently had the opportunity to attend a panel about conducting research in schools. As someone who has only ever done biological and chemistry-based lab work, I was eager to learn more about how research is conducted in other disciplines.

Doing research in schools is particularly challenging because it includes so many parties. The research goals must align with the school district’s priorities, collaboration must occur with the teachers, administrators and researchers about the design of the study and feasibility of implementations, and there must be cooperation from the students who are often young children unaware of the research going on.

Ultimately, the core role of schools is to educate children. Thus, in order to conduct research, the team needs to find a way to provide a clear benefit to schools for participation and make sure of protecting instruction time, reducing the burden on teachers.

The main purpose of the panel was to help Duke researchers better understand how to effectively interact and conduct research in schools. This was very well reflected in the four panelists Amy Davis, Cherry Johnson, Michele Woodson, and Holle Williams who each gave short, individual presentations.

Essentially,  the goal of a school is to provide high-quality education to the students. So to conduct research, researchers must find a way to make their goals applicable to the teachers.

Davis, the coordinator of grants, research, and development in Durham Public Schools explained that because of their large minority population, researchers often want to partner with them. Davis explained that researchers should strive to work collaboratively in a way that will yield what the researcher needs but also benefit the school. The focus of the teachers and administrators is not on research and they are not experts in things like research design.

She urged researchers to first reach out to her because she knows which schools would be a viable fit and can help provide the language to talk directly to them. Furthermore, she addressed that researchers sometimes need to have the flexibility to alter the research design when working in schools.

Johnson, the Director of Research and Grant Development in Johnston County Public Schools began by explaining how her district is driven by principles of relationships, relevance, and innovation.

She added that they are  “always interested in collab opportunities between universities and JCPS.”

However, studies that can aid in furthering their priorities, namely innovation, teacher recruitment and social and emotional learning will have a higher likelihood of being conducted successfully.

What makes the county so unique is that they are almost two districts within one.

“We still have notable lines between the haves and have nots,” Johnson added referring to large the socioeconomic differences between the Raleigh commuters and farm families.

To address some of these challenges, JCPS are participating in many partnerships with universities like NC State, UNC and Duke including a study with Dr. Leslie M. Babinski, associate research professor in the Sanford School of Public Policy.

Ultimately, university research is not a school district’s top priority. However, Woodson added that if the research has the ability to aid the school in accomplishing their goals then it increases the likelihood of success for both parties.

The last speaker was Holle Williams the Director of Main Campus Institutional Review Board at Duke University. Most schools require the approval of Duke’s IRB, which aims to protect the rights and welfare of human research subjects. Williams explained that their goal is to understand the intent of the researcher’s project.

“We want to make sure that what you are doing, what you are contemplating meets the definition of research” Williams stated.

Understanding intent allows then to distinguish research from other kinds of projects where research can help the school but also must contribute to the universal knowledge of a given education based topic.

A big emphasis of the talk was open communication. Both the school representatives and director of IRB highlighted that in order to most efficiently carry out a research project, the researchers should make sure to reach out to both the schools as well as main campus IRB. Through effective communication, strong partnerships can be built between the Duke community and local schools to conduct research that benefits both parties.

Alex Dehgan and The Snow Leopard Project

Traveling through war-torn areas at risk of encountering landmines, militia, and difficult terrain, Alex Dehgan was protected only by a borrowed Toyota Corolla. Dehgan, the Chanler Innovator in Residence at Duke, has spent much of his life overseas addressing conflict in Afghanistan through promoting wildlife conservation.

As a result, Dehgan has served in multiple positions within the U.S. Department of State, including the office of the secretary, and the bureau of Near Eastern affairs. There, he aided in addressing foreign policy issues in Iran, Iraq, and Egypt and contributed to the improvement of science diplomacy. Recently, he founded the Office of Science and Technology as the Chief Scientist at the U.S. Agency for International Development.

Dehgan Speaking at Duke

Dehgan recently gave a talk at Duke on the snow leopard project, an effort he spearheaded focusing on snow leopard (Panthera uncia)  and other wildlife conservation in Afghanistan. Because of the conflict, most people are not aware of the incredible wildlife and natural beauty within the country’s borders.

In his conservation efforts, Dehgan visited the Pamir, Karakoram, Hindu Kush, and Tien Shian mountain ranges hoping to learn more about the wildlife that lived there and the best way to promote their conservation. He used camera traps and collected scat to figure out species were in the area.

He began by talking about the Pamir mountains. Despite the fact that this is a very dangerous region to be, Dehgan ventured in ready to work with locals and discover the wildlife there. Once,  a member of his team asked if they could forgo checking the camera traps for the day because they were being bombed by the U.S. Army. However, it was worth it because Dehgan had the opportunity to work with locals and collect images as well as data on several unique species.

This included the Marco Polo sheep (Ovis ammon polii), enormous sheep that live in single-sex groups for most of the year. They only come together to mate and when they do, the males clash heads with one another for the ability to procreate. He was also able to find a markhor (Capra falconeri), which he prefers to call a “Twin-horn unicorn.” Markhor means snake eater, but the animal does not actually eat snakes. These animals are so valuable that a hunter once paid $110,000 to shoot one. Dehgan and his team were able to collect hair and genetic samples of musk deer (Moschus), which can be found in very steep areas of the Pamir mountains. These animals derive their name from the musk they produce which is often used in perfumes.

The area is known as Nuristan, the land of the enlightened, and is unique in that each valley has its own tradition, crafts, and even dialect. Dehgan and his team worked with people from the region and trained them to look for the specific animals

One of the most remarkable places Dehgan visited was Band-e Amir, which he described as looking like the grand canyon. The most unique natural aspect is a system of six lakes formed by the same process that creates stalactites and stalagmites. Above the lakes is an incredible mountain range and on top of the mountains are marine fossils because it used to be at the bottom of the sea. Here, Dehgan was able to use camera traps to collect images of ibexes (Capra ibex), Persian leopards (Panthera pardus saxicolor), and poachers. Poaching would eventually become one of Dehgan’s key focuses. Dehgan and his team also discovered Asiatic wild asses and assumed the presence of Asiatic leopards after finding their skins in the nearby villages.

Dehgan discovered that there was a massive trade in wildlife driven by the U.S. military. Skins of snow leopards and Persian leopards could be found all over Afghanistan as a part of illegal wildlife trade and other wildlife like Saker Falcons could be sold for up to $1 million.

As a result, Dehgan started a program around wildlife trafficking. A major part of his effort took place on Chicken Street, a busy shopping area where illegal animal skins could frequently be found. Dehgan worked closely with U.S. Military police, training them on how to identify furs.

Dehgan also worked with Afghani airport employees on how to inspect baggage for illegal furs. This resulted in the shut down of nearly all illegal fur trade, which Dehgan said was one of his biggest successes. In fact, one day while in Afghanistan, Dehgan received word that a fur trader wished to speak with him. Assuming they were angry at him for reducing their business Dehgan said that he actually feared for his life. However, it turned out that the fur trader simply wanted to be trained to identify illegal furs because they too wanted to protect Afghanistan’s wildlife.

Dehgan explained that Afghanistan was one of the easiest places he ever did conservation. This is because 80 percent of the human population is dependent on natural resources and thus when the wildlife fails, they fail. Because of this, they are eager to help aid in promoting conservation efforts.

Additionally, Dehgan was able to create the Wildlife Conservation Society’s Afghanistan Program which resulted in Afghanistan’s first and second national parks. Villages held local elections to set up a committee and to set up rules to govern the national parks.

Ultimately, his conservation work not only helped wildlife, but supported democracy by empowering, working with and training local communities.

Meet the Researcher Who Changed How We Care for Rape Survivors

One of the first things I was told during freshman orientation was that two out of every five young women at Duke experience some form of sexual assault during their four years as an undergraduate. Shortly after that, I was informed that as a Duke student, I was not allowed to protect myself with pepper spray, because it is banned by university policy.

At the 2019 Harriet Cook Carter Lecture, Ann Burgess, a professor of psychiatric mental health nursing at Boston College, reported that 25 to 30 percent of women and 10 percent of men will be sexually assaulted in their lifetimes, statistics that make our campus standard of 40 percent seem strikingly high in comparison. Burgess has devoted her life to the support of sexual assault survivors, and pioneered treatments for victims of such abuse. For the past fifty years, she has studied the traumatic effects of rape and violence on patients of all ages, and worked closely with the FBI Academy to research the underlying causes of such crimes. Her work at the FBI was so impactful, Netflix decided to write a TV series about her, a crime drama called “Mindhunter.” Talk about a powerful woman.

When she began her work with rape survivors in the 1970s, the world was a very different place. Public attitudes towards sexual assault were unsupportive and disapproving of victims. Rape thrived on prudery, silence, and misunderstanding. There were very few reported cases, low conviction rates of criminals, and plenty of victim blaming. “We just didn’t talk about these kinds of things,” Burgess recalled. “There was no public recognition.”

So have we advanced? Yes, absolutely. Throughout the years, Burgess says she has seen a crucial shift towards more support for survivors. She has helped the FBI develop better systems for criminal profiling, and testified countless times in court to ensure justice for survivors of all ages. Burgess has witnessed these court cases changing policies, and affecting the genesis of laws that will better protect citizens against rape and other violent crimes. She has studied lasting trauma in survivors, and used this research to implement new culturally and developmentally appropriate services for victims. She believes that, as a society, we are doing a much better job today to reduce stigma and support survivors, but that the work is not even close to finished.

Sexual assault is still an intensely pervasive issue in society. Rape can happen anywhere, to anyone, and Burgess thinks it all boils down to the cultural emphasis on aggression. “We’ve all become complacent to the violence in the world that we live in,” as panelist Lynden Harris put it. As a society, we perpetuate aggressive masculinity, often without even realizing it. And especially in communities like the military, where women and men alike are highly regulated and taught to avoid showing weakness at all costs, the stigma surrounding sexual assault is intense. Commander Alana Burden-Huber, director of public health services at the Cherry Point Naval Health Clinic, shared her perspective that it can be very difficult to come forward in such a world of conformity. She also mentioned that female jurors in sexual assault cases tend to be much harsher on female survivors than male jurors, and attributes this to the fact that female members of the military are constantly trying to be harder and more stoic, so as to parallel military men.

Panelist Mindy Oshrain, a consulting associate in the Duke Department of Psychiatry, quieted the crowd by sharing a moving quote from Maya Angelou: “There is no greater agony than bearing an untold story inside of you.” She reminded us that it is so important to listen to patients, and slow down enough to ask someone multiple times if they are doing okay. It is easy to forget this at a place like Duke, where we are all constantly moving 100 miles a minute, checking boxes as we rush from one activity to the next, but it can make all the difference to stop, and take the time to ask again- How are you really doing? What can I do to support you? Empathy has the power to change the world.

As a sophomore, I now live in a building full of young women on the edge of Central Campus, on a street that is only serviced by Duke transportation in one direction. Just a few months ago, I woke up to a Duke Alert message on my phone, which informed me that a violent rape crime had occurred in the night, just fifty yards from my apartment. While we may have come a long way since the 1970s, the unavoidable fact remains that as young women living in this world, we are not safe. Let’s change that.

The Importance of Moms

Emily Bray, Ph.D., might have the best job ever. Since earning her bachelor’s at Duke in 2012, she has been researching cognitive development in puppies, which basically means she’s spent the last seven years playing with dogs. If that’s not success, I don’t know what is.

Last Friday marked the 10th birthday of Duke’s Canine Cognition Center, and the 210th birthday of Charles Darwin. To celebrate, Brian Hare, Ph.D., invited former student Bray back to campus to share her latest research with a new generation of Duke undergraduates. The room was riveted — both by her compelling findings and by the darling photos of labs and golden retrievers that accompanied each slide.

During her Ph.D. program at the University of Pennsylvania, Bray worked with Robert Seyfarth, Dorothy Cheney, and James Serpell to investigate the effects of mothering on puppy development. For her dissertation, she studied a population of dog moms and their puppies at The Seeing Eye, Inc. The Seeing Eye is one of the oldest and largest guide dog schools in the U.S. They have been successfully raising and training service dogs for the blind since 1929, but like most things, it is still an imperfect science. Approximately half of the puppies bred at The Seeing Eye fail out of program. A dog that completes service training at The Seeing Eye represents two years of intensive training and care, and investing so much time and money into a dog that might eventually fail is problematic. Being able to predict the outcomes of puppies would save a lot of wasted time and energy, and Emily Bray has been doing just this.

Through her work at The Seeing Eye, Bray found that, similar to humans, dogs have several types of mothering styles. She discovered that dog moms tend to fall somewhere on the spectrum from low to high maternal involvement. Some of the moms were very involved with their puppies, and seldom left their side. These hovering moms had high levels of cortisol, and became quite stressed when separated briefly from a puppy. They coddled their children, and often nursed from a laying down position, doing everything they could to make life easy for their babies. On the other side of the spectrum, Bray also observed moms that displayed much more relaxed mothering. They often took personal time, and let their puppies fend for themselves. They were more likely to nurse while sitting or standing up, which made their children work harder to feed. They were less stressed when separated from a puppy, and also just had generally lower levels of cortisol. Sound like bad parenting? Believe it or not, this tough love actually resulted in more successful puppies.

Duke’s very own assistance dogs in training!

As the puppies matured, Bray conducted a series of cognitive and temperament tests to determine if maternal style was associated with a certain way of thinking in the puppies. Turns out, dogs who experienced high maternal care actually performed much worse on the tests than dogs who were shown tough love when they were young. At The Seeing Eye graduation, it was also determined that high maternal care and ventral nursing was associated with failure. Puppies that were over-mothered were more likely to fail as service dogs.

Her theory is that tough love raises more resilient puppies. When mom is always around, the puppies don’t get the chance to experience small stressors and learn how to deal with challenge. The more relaxed moms actually did their kids a favor by not being so overbearing, and allowed for much more independent development.

Bray is now doing post-doctoral research at the University of Arizona, where she is working with Canine Companions for Independence (CCI) to determine if maternal style has similar effects on the outcomes of dogs that will be trained to assist people with a wide range of disabilities. She is also now doing cognition and temperament tests on moms pre-pregnancy to determine if maternal behavior can be predicted before the dogs have puppies. Knowing this could be a game changer, as this information could be used for selective breeding of better moms.

If you got the chance to hang out with puppies Ashton, Aiden, or Dune last semester, you have an idea of how awesome Bray’s day-to-day work is. These pups were bred at CCI, and sent to Duke to be enrolled in Duke Puppy Kindergarten, a new program on campus run through Duke’s Canine Cognition Center. Which of these three will make it to graduation? I’ve got money on Ashton, but I guess we’ll have to wait and see.

The bottom line according to Bray? “Mothering matters, but in moderation.”

An Indirect Path to Some Extreme Science

Dr. Cynthia Darnell’s path to becoming a postdoctoral researcher in the Amy Schmid Labat Duke University was, in her words, “not straightforward.”

Dr. Cynthia Darnell is a Postdoc at Duke, studying ‘extremophiles.’

At the start of her post-high school career, Darnell had no clue what she wanted to do, so she went to community college for the first two years while she decided. She had anticipated that she was going to go to college as an art major, but had always enjoyed biology.

While at community college she took a couple biology courses. She transferred to another college where she took a course in genetics and according to her, “it blew my mind.” While at the college she took a variety of different biology courses. Her genetics professor’s wife was looking for a lab technician in the microbiology lab she ran. After Darnell worked there for two years, she decided to go to graduate school and had a whole list of places/universities she could attend.

However, after going to a conference in Chicago and meeting her future graduate advisor, Darnell made the decision to go to Iowa for six years of Graduate school. She ended up in the Schmid Lab at Duke University for her “postdoc” after her boss had recommended the lab to her.

Previously, Darnell had done research on the connectedness of genetic pathways in halophilic extremophiles — bacteria that lived in extremely salty conditions. She developed projects to understand the how their genetic network sends and receives signals.

Darnell is continuing that research at Duke while also looking at the effects of different environmental factors on growth and the genetic network using mutant halophilic extremophiles.

There are generally three different paths Darnell’s day in the lab can take. The first path is a bench day. During a bench day, she will be doing experiments looking at growth curves, microscopes or RNA extracts. The second path is a computational day in which she will do sequencing to look at gene expression. The third option is a writing day in which she spends a majority of her time writing up grants, papers, and applications.

Dr. Darnell wishes to open up her own lab in the future and serve underprivileged students in underserved areas. She wishes to do more research in the area of archaebacteria because of how under researched and underrepresented it is in the scientific community. Dr. Darnell hopes to study more about the signaling networks in archaebacteria in her own lab someday.

She especially wishes to be able to open her lab up to underprivileged students, exposing them to the possibilities of research and graduate programs.
