Acknowledging America’s Unspoken Caste System

Sticky post

Pulitzer Prize-winning author Isabel Wilkerson took the Page Auditorium stage on February 22 to discuss her most recent book, “Caste,” and its implications for modern-day America. Co-hosted by the Sanford School of Public Policy and the Mary Lou Williams Center for Black Culture, the event featured a lecture and Q&A section.

A caste system is an artificial construction, a fixed and embedded ranking of human value that sets the presumed supremacy of one group against the presumed inferiority of other groups.”

Isabel Wilkerson

When Wilkerson first published “Caste: The Origin of Our Discontents,” it spent 55 weeks on the U.S. best sellers list. Barack Obama put it in his 2020 reading list, and Oprah Winfrey sent the book to Fortune 500 CEOs around the world. Since then, it has sold over 1.56 million copies and has become a #1 New York Times best seller.

In other words: “Caste” is the Beyoncé of books.

Wilkerson began by reminding the audience of the recentness of our country’s progress. “In recent times it’s not been unusual to hear people say something along the lines of ‘I don’t recognize my country,’ Wilkerson began. “And whenever I hear that I’m reminded that tragically not enough of us have had the chance to know our country’s true and full history.” She described the U.S. as a patient with a preexisting health condition, asserting that America has been plagued by racism since its inception. Like a chronic disease, these roots continuously persist and flare up.

For context, the United States is 247 years old. A full 89 of those years were spent in slavery and 99 were spent in the Jim Crow era. For 227 years, race was considered an innate, factual construct (until the completion of the Human Genome Project in 2003). Racial injustice isn’t a period of history in this country, it is this country’s history.

Wilkerson furthered her point by detailing the dehumanizing customs of the Jim Crow caste system in the South. “You could go to jail if you were caught playing checkers with a person of a different race,” Wilkerson said. “That means that someone had to have seen a Black person and a white person in some town square… And they felt that the entire foundation of southern civilization was in peril and took the time to write that down as a law.” Before the late 20th century, there was even a separate Black and White Bible to take an oath in court. “That means that the very word of God was segregated in the Jim Crow South,” Wilkerson said.

She described this system of racial oppression as an “arbitrary, artificial, graded ranking of human value” – in other words, a caste system. She highlighted how race was weaponized by early colonists to determine “who would be slave or free, who would have rights and no rights.”

This caste system wasn’t just a “sad, dark chapter,” Wilkerson said. It’s “the foundation of the country’s political, social, and economic order.”

For 6 million Black southerners, the caste system became so suffocating that migrating across the country (a movement called The Great Migration), seemed like the only path to freedom. “No other group of Americans has had to act like immigrants in order to be recognized as citizens,” Wilkerson said. “So this great migration was not a move. It was not about moving. It was a defection. A seeking of political asylum within the borders of one’s own country.”

But the U.S. caste system extends far past slavery and Jim Crow. Take the vastly different police response to the January 6 Capitol riot compared to BLM protests during the summer of 2020. “We alive today are tasked with explaining to succeeding generations how…a rioter could deliver the Confederate flag farther than Robert E. Lee himself.” The United States has never adequately dealt with its racist history, which is why it keeps repeating itself.

In a powerful call to action, Wilkerson urged the audience to honor these histories and “teach the children so that we can end these divisions now with the next generation.” She shared the aspiration of novelist Richard Wright: “To transplant in alien soil…and perhaps just perhaps to bloom” in a more equitable world.

The HIV/AIDS Epidemic: Revisiting the Early Days of a Global Health Crisis

Sticky post

On June 5, 1981, the Centers for Disease Control and Prevention reported the first cases of a mysterious disease afflicting young, otherwise healthy men in a tiny suburb of Los Angeles, California. The disease, now known as AIDS, would go on to infect 85.6 million people around the world, sparking an epidemic that persists to this day.

On February 6, 2024, Duke’s Global Health Institute hosted a conversation with Dr. James Curran and Dr. Kevin M. De Cock, both former leaders at the CDC, about their experiences on the frontlines of the AIDS crisis in the earliest days of this epidemic. The conversation was moderated by Dr. Chris Beyrer and Dr. Nwora Lance Okeke, two Duke researchers in infectious disease.

Pictured from left to right: Dr. James Curran and Dr. Kevin M. De Cock

The Origin of the Epidemic

The first cases of AIDS were reported by Dr. Michael Gottlieb, a young immunologist from UCLA. His groundbreaking findings, published in the CDC’s Morbidity and Mortality Weekly Report, described “previously healthy gay men from Los Angeles, San Francisco, and New York, who presented with rare opportunistic infections,” said De Cock. These infections, known as PCP (Pneumocystis carinii pneumonia) and KS (Kaposi’s sarcoma), were extremely rare. Upon observation, Gottlieb identified a startling commonality among the cases: they were all sexually active gay men.

These findings “didn’t fit into any organizational unit at the CDC,” so a multispecialty task force was formed. Led by Curran, it recruited experts in STIs, parasitology, virology, cancer, and more.

Tracking the Epidemic

At the start of the epidemic, cases were phoned into the CDC by individual doctors. But this quickly became inadequate. The epidemic was growing fast, and CDC phone lines could not keep up. “The CDC, therefore, developed a surveillance case definition for the syndrome,” De Cock explained. “Cases meeting this definition were reported through health departments to the CDC.”

“I think we were able with the case definition for surveillance, to take advantage of the fact that all of these conditions were very serious and so unusual that the physician would say ‘I’ve never seen anything like it,’…,” Curran said. “The other conditions were far less specific and far less useful for tracking the disease.”

In October 1981, these tracking protocols helped identify AIDS as a sexually transmitted disease. A national case-control study found that sexual activity was a leading risk factor, and a cluster of cases in 10 US cities linked via sexual contact was discovered. “People just didn’t want to believe it,” Curran said. “They wanted to believe that it wasn’t something transmissible.” 

Expanding Epidemic

Over the next year, the epidemic expanded to include injection drug users, heterosexual partners of bisexual men, people of Haitian descent, and infants. But perhaps most surprising was the transmission occurring through blood transfusion. In December 1982, a case of AIDS-like illness was reported in a 20-month-old infant after receiving blood from a donor who later developed the virus.

“Until that December report of the infant, the mainstream media had actually paid very little attention to AIDS. But that suddenly changed,” said De Cock. “While AIDS was seen as a problem of marginalized groups… it was easy to ignore. But anyone might need a blood transfusion.”

In the following years, rumors surrounding transmission and contact sparked nationwide panic. Fear of contracting the disease caused AIDS patients to lose their jobs and housing. Although the CDC provided up-to-date information on the nature of the virus, quelling public fear was extremely difficult. “AIDS proved that you can’t separate prevention and treatment,” Curran explained.

Modern AIDS Era

As we get close… to 100 million HIV infections since the epidemic began- have we done as well as we should have?”

Dr. Kevin M. De Cock

In 1991, researchers successfully identified HIV (Human immunodeficiency virus) as the underlying cause of AIDS. Since then, scientific understanding of the disease has greatly improved. “Our success has made AIDS more normal, which has robbed the disease of some of its mystique,” De Cock expressed. However, there is still no known cure for AIDS. The disease is a lifelong battle that wreaks havoc on the people it infects.

De Cock and Curran’s contributions to the AIDS epidemic fundamentally shaped our understanding of the virus. Their work shines a light on the importance of frontline research and support. Their book, entitled ‘Dispatches from the AIDS Pandemic: A Public Health Story,’ is available to read here.

Your AI Survival Guide: Everything You Need to Know, According to an Expert

Sticky post

What comes to your mind when you hear the term ‘artificial intelligence’? Scary, sinister robots? Free help on assignments? Computers taking over the world?

Pictured: Media Architect Stephen Toback

Well, on January 24, Duke Media Architect Stephen Toback hosted a lively conversation on all things AI. An expert in the field of technology and media production, Toback discussed some of the practical applications of artificial intelligence in academic and professional settings.

According to Toback, enabling machines to think like humans is the essence of artificial intelligence. He views AI as a humanities discipline — an attempt to understand human intelligence. “AI is really a digital brain. You can’t digitize it unless you know how it actually works,” he began. Although AI has been around since 1956, the past year has seen an explosion in usage. ChatGPT, for example, became the fastest-growing user application in the world in less than 6 months. “One thing I always talk about is that AI is not gonna take your job, but someone using AI will.”

During his presentation, he referenced five dominant AI platforms on the market. The first one is ChatGPT, created by OpenAI. Released to the public in November 2022, it has over 100 million users every single month. The second is BardAI, which was created by Google in March 2023. Although newer on the market, the chatbot has gained significant traction online.

Pictured: Toback explaining the recent release of Meta’s AI “Characters.”

Next, we have LLama, owned by tech giant Meta. Last September, Meta launched AI ‘characters’ based on famous celebs including Paris Hilton and Snoop Dog, which users could chat with online. “They’ve already started commercializing AI,” Toback explained.

Then there’s Claude, by Anthropic. Claude is an AI assistant for a variety of digital tasks. “Writers tend to use Claude,” Toback said. “Its language models are more attuned to text.”

And finally on Toback’s list is Microsoft Copilot, which is changing the AI game. “It’s integrating ChatGPT into the apps that we use every day. And that’s the next step in this evolution of AI tools.” Described on Microsoft’s website as ‘AI for everything you do,’ Copilot embeds artificial intelligence models into the entire Microsoft 365 suite (which includes apps such as Word, Excel, PowerPoint, and Outlook). “I don’t have to copy and paste into ChatGPT and come back- It’s built right into the app.” It’s also the first AI tool on the market that provides integration into a suite of applications, instead of just one.

Pictured: A presentation created by Toback using Copilot in PowerPoint

He outlined several features of the software, such as: summarizing and responding to email threads on Outlook, creating intricate presentations from a simple text document in PowerPoint, and generating interview questions and resume comparisons in Word. “There’s a great example of using AI for something that I have to do… but now I can do it a little bit better and a little bit faster.”

Throughout his presentation, Toback also touched on the practical use of ChatGPT. “AI is not perfect,” he began. “If you just ask it a question, you’re like ‘Oh that sounds reasonable’, and it might not be right.” He emphasized challenges such as the rapidly changing nature of the platform, inherent biases, and incorrect data/information as potential challenges for practical use.

“Rather than saying I don’t know, it acts a lot like a middle schooler and says it knows everything and gives you a very convincing answer.”

Stephen Toback

These challenges have been felt nationwide. In early 2023, for example, lawyers for a federal court case used ChatGPT to find previous claims in an attempt to show precedent. However, after presenting the claims to a judge, the court found that the claims didn’t actually exist. “It cited all of these fake cases that look like real citations and then the judge considered sanctions, ” said Toback. ‘AI hallucinations’ such as this one, have caused national controversy over the use and accuracy of AI-generated content. “You need to be able to double-check and triple-check anything that you’re using through ChatGPT,” Toback said.

So how can we use ChatGPT more accurately? According to Toback, there are a variety of approaches, but the main one is called prompt engineering: the process of structuring text so that it can be understood by an AI model. “Prompts are really the key to all of this,” he revealed. “The better formed your question is, the more data you’re giving ChatGPT, the better the response you’re going to get.” Below is Toback’s 6-step template to make sure you are engineering prompts correctly for ChatGPT.

Pictured: Toback’s template for ChatGPT prompt engineering

So there you have it — your 2024 AI survival guide. It’s clear from the past few years that artificial intelligence is here to stay, and with that comes a need for improved understanding and use. As AI expert Oren Etzioni proclaims, “AI is a tool. The choice about how it gets deployed is ours.”

Carrying on Dr. King’s Legacy: The Fight for Equity in Obesity Treatment

“Of all the forms of inequality” Dr. Martin Luther King Jr. once said in a 1966 press conference, “injustice in health is the most shocking and the most inhumane.”

In honor of King’s impact on public health, Duke’s dean of Trinity College Dr. Gary G. Bennett delivered a powerful address Jan. 12 at the Trent Semans Center. Entitled ‘You have to Keep Moving Forward: Obesity in High-Risk Populations,’ Bennett discussed America’s Obesity Epidemic, and its disproportionate effects on Black women.

“More than 40% of the American population has obesity,” Bennett began. Incidence rates among Black women are the highest and have been since the epidemic began in 1955. “These disparities have not closed, and in many cases, they’ve widened over the years,” Bennett said.

Raisi-Estabragh 2023

Type two diabetes, hypertension, and cardiovascular disease are just some of the health risks associated with obesity. Compared to other racial groups, Black women are more likely to suffer from these conditions, as well as die from their effects. Furthermore, it appears that the efficacy of treatment options is significantly lower for patients of African descent.

But why do such disparities exist in the first place? According to Bennett, they can be attributed to a range of internal and external factors. “There certainly are physiological variations that are worth noting here, which is perhaps a challenge in all of obesity research.”

Research published in the journal Nature in 2022 found that, while there are different forms of obesity, that have shared ‘genetic and biological underpinnings.’ Environmental factors are also driving disparities. Black women are “exposed to more obesogenic environments, food desserts,” Bennett explained.  With limited access to affordable and nutritious food, options for healthy eating are slim.

But perhaps most interestingly, Black women also have a range of sociocultural factors at play. “There are fewer within-group social pressures to lose weight,” Bennett maintained. Other sociocultural factors include higher body image satisfaction and higher weight misperception. “This is problematic in some ways,” he continued. While it protects against certain eating disorders and low self-esteem, “It does challenge your ability to achieve weight loss.”

For Black women, obesity is a complex public health issue that needs to be addressed.

But how? From medication to surgery, there are myriad potential treatment options. According to Bennett, however, the real key is lifestyle intervention. “It really is the foundation.” Comprised of three parts: reduced calorie diet, physical activity, and self-monitoring, lifestyle intervention is able to reach the widest range of participants.

Like other treatment options, the lifestyle intervention route shows racial disparities in its outcomes. Because of this, Dr. Bennett’s work focuses on developing methods that are designed with Black patients in mind.

At the forefront of his research is a new online intervention called iOTA, which stands for Interactive Obesity Treatment Approach. “This is a digital obesity approach that we designed specifically for high-risk populations.” The platform personalizes weight loss goals and feedback, which assist in program retention.

In addition, participants are equipped with coaching support from trained medical professionals. “This IOTA approach does a bunch of things,” Bennett said. “It promotes weight loss and prevents weight gain, improves cardiometabolics,” along with a host of other physical benefits. Results also show a reduction in depressive symptoms and increased patient engagement. Truly incredible.

Scholars like Bennett have continued the fight for public health equity- a fight advocated for by Dr. King many years ago. For more information on Bennett and his work, you can visit his website here.

Is The World In Crisis?

According to a recent NPR/Ipsos poll, nearly 70% of Americans believe that U.S. democracy is “in crisis and at risk of failing.” Two out of every three respondents also agree that U.S. democracy is “more at risk” now than it was a year ago. 

These fears are not unfounded. For the past three years, the United Nations Human Development Report has issued increasingly grave warnings for the state of the world. The warnings focus specifically on the Anthropocene, rising inequality, and growing polarization, conveying themes of both uncertainty and hope.

Pictured above: The 2022 Human Development Report.

On March 22nd, the director of the United Nations Human Development Report Office, Dr. Pedro Conceição, discussed his perspective at Duke University. The fireside chat was hosted by the Duke Center for International Development and the South-North Scholars, and was moderated by Dr. Anirudh Krishna.

“People should be able to live their lives at their full potential,” Dr. Conceição began. “When you look at the world and see how people are living their lives compared to how they should be living their lives, you get the need for human development.”

First introduced in 1990, the Human Development Report focuses on improving the quality of human life, rather than just the economy in which human beings live. The report emphasizes three pillars: people, opportunity, and choice. “Living life to your full potential is essentially about human freedom,” Dr. Conceição said. It is these freedoms that are at risk as the conditions in the Human Development Report worsen.

“We need to dig more deeply into why we aren’t taking action,” Conceição maintains. He explains that current efforts to spark change are too factual. Governments and corporations are focused too heavily on raising awareness and should pivot to trying to take tangible steps.

Political division is also a major source of stagnation, as those who lie on either side of the spectrum tend to be more insecure in their views of the future. Because of these obstacles, it requires a “more complex and unusual way of trying to understand these problems.”

The report has citizens from around the world concerned about potential declines in the quality of well-being. But Dr. Conceição asserts that the reports are meant to communicate hope.

“It’s precisely because we are having this level of uncertainty that this becomes even more relevant,” he said. In fact, it is this uncertainty that the report will build off of for future publications. The literature will dig deeper into novel areas of uncertainty, to figure out the best way forward.

Dr. Conceição urges students to invest in the United Nations and its initiatives, as it is crucial in creating a better outlook on the future. As Abraham Lincoln once expressed, “The most reliable way to predict the future is to create it.”

Why There Has Never Been Infrastructure ‘Justice for All’

Since coming to Duke nine years ago, I gained the realization that all rural communities are virtually the same… the infrastructure neglect is still the same.”

Catherine Coleman Flowers

Catherine Coleman Flowers is no stranger to action. Since the start of her career, she’s accomplished everything from working as the Vice Chair of the White House Environmental Justice Advisory Council to founding the Center for Rural Enterprise and Environmental Justice. An internationally recognized advocate for public health, Flowers has worked tirelessly to improve water and sanitation conditions across rural America.

On February 9th, Duke University students got to hear from Flowers in a powerful seminar sponsored by Trinity College. A Practitioner in Residence at the Nicholas School of the Environment, Flowers discussed her incredible activism journey.

“I became an activist very, very young,” she said. Her family heritage nurtured her love for the environment early on, as well as her home state of Alabama. In high school, she began to read about the sanitation crisis happening in rural Alabama, Lowndes County in particular.

“I learned that poor people (there) were being targeted for arrest because they couldn’t afford sanitation systems,” Flowers said. The poverty rate in this historically Black county is double the national average, and sewage treatment is not provided for many residents. For those who can afford sanitation systems, they are often far from adequate, such as poorly maintained septic tanks. Issues like exposure to tropical parasites and improper installations are rampant throughout the county.

“It builds upon the structural inequalities that make sure these areas remain poor,” Flowers said. Across the US, millions of rural areas face the same complications. From places like ‘Cancer Alley’ in New Orleans to the city of Mount Vernon in New York, sanitation systems are failing miserably.

“We saw families that couldn’t live in their houses half the time because of the sewage that was running into their home,” Flowers explained. Unsurprisingly, almost all of the areas facing these issues are home to minority communities. “The narrative used to be, ‘they don’t know how to maintain it,’ but that isn’t true. The technology isn’t working at all.

In November of 2021, Flowers filed the first-ever civil rights complaint against sanitation in Lowndes County. Thanks to her, as well as other prominent community activists, the issue garnered nationwide attention. In less than a year, the county received a $2.1 million grant from the USDA to begin solving the sewage crisis. Similar funding efforts have also been seen in Mount Vernon. “That is an example of what a solution can look like,” Flowers said.

“That’s the kind of power that you have as a Duke student,” Flowers said in closing. With almost one million dollars available for student funding annually and access to one of the greatest networks in the world, Duke students are in a remarkable position to make a change, she said. In North Carolina, counties like Duplin and Halifax are in need of outside help. “Growing up in the computer age, you can bring those skills needed to assist those applying for funds.”

Duke’s Environmental Justice Network

So, what can you do? Above all, Flowers emphasizes the importance of leading from behind. ” Don’t go in the community and try to lead from the front… People from the community need to be involved from the design to the implementation.”

As students, our assistance is needed in the form of support. From assisting with grant applications, to utilizing our network access to spread the word, there are so many ways to get involved. True equity is found not when we speak for the community, but rather when we strengthen the community’s ability to speak for itself.

It’s Their Future and Gen Z Has Already Seen a Lot

Young people have the power to generate change, whether they know it or not.

At least that was the sentiment expressed by the Director of Polling at the Harvard Institute of Politics, John Della Volpe at a seminar earlier this month. A leading authority on the intersection of young Americans and political influence, Della Volpe discussed the key role Generation Z will play in the 2022 and 2024 elections.

But does Generation Z really have what it takes to change the course of American politics?

“We spend a lot of time talking about Gen Z, and not enough time talking to you,” Della Volpe began as he addressed a crowd of young Duke students. “This is one of the rare occasions where I’m going to be doing most of the talking rather than most of the listening.”

Stanford Researcher Roberta Katz describes Generation Z — those born between 1997 and 2012 — as a highly collaborative cohort with a pragmatic attitude about generational issues like political engagement.

Exit Polls from NBC reveal that Gen Z was responsible for more than 9% of total votes in the 2020 presidential election, with that number only expected to grow. In Georgia and Arizona, young voters turned out to be critical for President Joe Biden’s victory, Della Volpe said.

Exit Polls From NBC show 2020 total votes for Biden compared to Trump, with Generation Z voting for Biden two-to-one.

He urges Gen Z to “remind elected officials that you did change things and that you will continue changing things.” Della Volpe predicts that Gen Z’s choices will also be crucial in the 2022 midterms.

Occupy Wall Street, the election of Trump, the Parkland Shooting, Greta Thunberg, and the killing of George Floyd were five events that Della Volpe believed were crucial in shaping this trajectory, as well as Gen Z’s political view as a whole.

“We have to look collectively at what you as a cohort saw and how that’s affecting you. In fact, I think that’s a far better way to think about our politics than what state you are in.”

The way parents think about bills and taxes, the way that weighs on your shoulders, that’s the way we think about living and dying.

Gen Z woman in conversation with John Della Volpe

“No generation in 70 years has dealt with more chaos, more trauma, more struggle before your brain is even fully developed,” Della Volpe asserted. He maintains that Generation Z is dealing with extremely complex issues much earlier than other generations.

Research from the American Psychological Association bears this out, indicating that Gen Zers are currently the most stressed demographic of people in the United States. They are also significantly more likely to rate their mental health as poor in comparison to other generations.

“I’m very cognizant of not putting any more pressure on you,” said Della Volpe. “You are already doing such a good job of managing yourselves and managing your situation.”

John Della Volpe’s book, published earlier this year.

Generation Z is managing so well, in fact, that Della Volpe argues they are essential to the success of US politics moving forward. In his book ‘Fight: How Generation Z is Channeling Their Fear and Passion to Save America,’ Della Volpe argues that the challenges unique to Gen Z prepare them to take control of their future in this nation.

Thanks to Della Volpe the answer is overwhelmingly clear: Gen Z does have what it takes to turn this nation around. So get out there and vote!

Materials For a Changing World… What is That?

Everything in our world is made from materials, meaning life is enabled by material development and efficiency. In today’s society, from constant technological revolution to the global pandemic, life as we know it is always evolving. But as the world around us evolves, the materials around us also need to evolve to keep up with current demands. But how? As a part of Duke University’s annual Research Week on Feb. 3, researchers from a multitude of practices offered their wisdom and research.

Moderated by Dr. Catherine L. Brinson, Ph.D., the panel hosted three Duke Scholars and their research on ‘Materials for a Changing World’. “The development of new materials can really be key in solving some of the more critical challenges of our time,” Brinson maintained.

Dr. David Beratan explaining his research on bio-machines and their material efficiency.

The first scholar to present was R.J Reynolds distinguished professor of chemistry, Dr. David N Beratan, Ph.D. His research concerns the transition from soft, wet, and tiny research machines to more durable, long-term research machines in the science field. “The machines of biology tend to be stochastic and floppy rather than deterministic and hard,” Beratan began. “They’re messy and there are lots of moving parts. They’re intrinsically noisy and error-prone, etc…They’re very different from the kinds of things you see under the hood of your car, and we’d really like to understand how they work and what lessons we might derive from them for our world.” His complex research and research group have aided in bridging the gap in knowledge regarding the transition of biological functional machines to synthetic ones.

Dr.Rubinstein presenting his research on materials at Duke’s Pratt School of Engineering in 2019.

The panel continued with Aleksandar S. Vesic Distinguished Professor in mechanical engineering, Dr. Michael Rubinstein, Ph.D. His research involves the development of self-healing materials across multiple spectrums. “What you want to think about is materials that can heal themselves,” he stated. “If there’s a crack or a failure in a material, we would like the material to heal itself without external perturbation involvement. So it could be done by the other diffusion of molecules across some physical approaches, or by a chemical approach where you have bonds that were broken to the form.” His research on this possibility has made strides in the scientific field, especially in a time of such ecological stress and demand for materials.

Dr. Segura talking with Dr. Brinson on her research involving self-healing materials.

The panel concluded with biomedical engineering professor Dr. Tatiana Segura, Ph.D. Segura talked about work they are doing at their lab regarding materials that can be used to heal the human body after damage or injury. She began by mentioning that “we are a materials lab and that’s what we’re interested in designing. So what are we inspired by? Well, we are really inspired by the ability of our body to heal.” At her lab, a primary motivation is healing disabilities after a stroke. “Sometimes you have something that you deal with for a long time no matter how your body healed. And that inspires us to consider how do we actually engage this process with materials to make it go better and actually make our body heal in a way that we can promote repair and regeneration.” Understanding this process is a complex one, she explained, but one that she believes is crucial in understanding the design of the material.

‘Materials for a Changing World’ was yet another extremely powerful speaker series offered this year during Duke Research Week. Our world is changing, and our materials need to keep up. With the help of these experts, material innovation has a bright future.

The Climate Crisis is Imminent. These Experts Offer Solutions.

In April of 2019, the first government declared climate change to be a national emergency. Since then, over 1,900 local governments and more than 23 national governments have expressed the same sentiment.

A 2021 report released by the IPCC labeled climate change a ‘code red’ for humanity, and every day more than 2 million people search the term ‘climate crisis’ on Google. So it’s apparent, the climate crisis is imminent. What’s the solution? Experts at Duke’s annual Research Week posed their research-based solutions during a virtual panel hosted on February 1st. (View the Session)

The panel, mediated by Biology professor Mohamed Noor, began with a solution posed by professors Mark Borsuk and Jonathan Wiener. Known as solar radiation modification, SRM is “an attempt to moderate global warming by intentionally increasing the amount of incoming sunlight that is reflected by the atmosphere back to space,” according to Borsuk. Its primary technique is stratospheric aerosol injection. Wiener explained that their research is “trying to understand the risk… And we’re working to study these multiple impacts because all too often, as we’re all familiar with human decision making at the individual level or the governmental public policy level tends to focus on one thing at a time.” However, even with possible governance challenges at play, their research poses an extremely cheap yet effective solution for avoiding some of the worst impacts of climate change.

Dalia Patino Echeverri’s presentation on GRACE, an energy solution.

Next up on the panel was Dalia Patino Echeverri, an associate professor at Duke’s Nicholas School of the Environment. She began by ruminating on the challenges faced in Texas after the snowstorm last year, and how climate change intensified those challenges. Her research focuses on how to address the electricity issues that climate change is producing in our nation, through a system called ‘GRACE’. ‘GRACE’ is a power grid that is risk-aware for clean, smart energy usage.

“It considers the forecast of electricity, the amount of load on the forecast of electricity generation from wind and sun of resources, and looks at the availability of conventional resources to schedule this commercial resources.” said Echeverri. Its operating system is extremely intelligent minimizing expected value and total cost of energy during times of climate crisis.

Brian Silliman’s presentation on Duke Restore.

Finally, a solution was presented from Brian Silliman, the Rachel Carson Distinguished Professor for marine biology. He introduced a more grassroots approach to climate restoration, called Duke Restore.

“A lot of our research and those of others have shown that the presence of restored marine environments greatly protects human societies on the coastline from increasing threat storm surge, and flooding generated in large part by climate change impacts, etc.” Silliman began.

Duke Restore aims to go out into ecosystems and restore the shorelines that have been lost, indirectly aiding in climate crisis alleviation. Silliman is currently collaborating with governments and other conservation organizations to help change the way they plan to restore these ecosystems from the bottom up. ““We’re doing this here in North Carolina with the US Marine Corps, changing the planting designs to switch the restoration trajectory from failure to success.”

Kay Jowers explaining her ideas for a more equitable approach to policy solutions.

Kay Jowers, a Senior Policy Associate at the Duke Nicholas Institute for Environmental Policy Solutions, closed out the panel event with some final thoughts.

“My charge is to give you some food for thought about creating a more supportive environment for environmental and climate justice at Duke,” she began. She explained the need for action as compared to documentation and explained that equitable approaches are needed to avoid a climate disaster.

“In the world of Environmental Justice Studies, the communities, and the scholars have been calling for less problematization and documenting of problems, and more orientation towards solutions.” Her sentiments resonated deeply with the theme of the panel, as solution-based research is of paramount importance in the 21st century.

The Duke Research Week panel on climate change solutions posed tangible explications for the ever imminent climate crisis happening around the world. Though climate change is apparent now more than ever, researchers like these hold the solutions for the future.

Introducing Muser – A Better Way to Find Student Research

An effortlessly simple research platform where Duke students and Duke research projects can connect? Yes, please!

If you are anything like me, Duke University’s incredible research opportunities were extremely enticing when considering this school. One of the top 10 research institutions in the United States, Duke University’s research community spends over 1 billion dollars annually to fund its projects, which includes notable research facilities like the Duke Center for Human Genetics, the Duke Cancer Institute, the Duke Center for AIDS Research, and the Duke Human Vaccine Institute.

However, the amount of opportunity in this area can be overwhelming to approach, and as a student you often have no clue where to start.

That’s where Muser comes in.

Duke introduces: Muser.com

Muser is a website created by Sheila Patek, a Duke biology professor who used grant money from the National Science Foundation to create a more equitable and straightforward way to connect undergraduates with professors with research opportunities. The resource allows researchers to post ongoing research positions with a direct application through the website.

Muser can sort research projects by compensation, hours, year, and project category, simplifying Duke’s incredibly complex research community by a lot.

“Muser posts research projects in 4 rounds throughout the year, a Fall round (August), a late Fall round for Spring projects (October/November), a Spring round for Summer projects (February/March), and a Spring round for Fall projects (March/April),” according to its website. Muser makes it easy to accommodate research positions into the part of your semester that works with your busy schedule.

I connected with some Duke students who have found success with the growing research platform, and though their interests were diverse, the success was all-encompassing.

“My experience with my Muser Project for the summer of 2021 was great overall,” said Elaijah Lapay, class of 2025. “It was essentially a history research assistantship helping a professor in the history department conduct research on elderly and eldercare in North Carolina. I was able to go to the NC State archives as well as archives across eastern North Carolina to really dive into the question of treatment of the elderly during the 20th century.”

Lapay’s research is so fruitful that the professor, James Chappel, the Gilhuly Family Associate Professor of History, is continuing to pursue this project for the rest of the school year. “I truly felt one-of-a-kind… I definitely feel like I’ve learned a lot and it’s sparked a passion in me for geriatrics and eldercare.”

A look inside Dr. Laurie Sanders’s lab here at Duke University.

“I got the chance to work in the Sanders lab under principal investigator Dr. Laurie Sanders and post-doctorate Dr.Claudia Gonzalez-Hunt!” said Shreya Goel, class of 2025. This lab was the first to link a genetic mutation to mitochondrial DNA damage which was ultimately discovered to be a marker for sporadic Parkinson’s disease.

“I get to work with human cells to induce and track mitochondrial and nuclear DNA mutations to determine their effect on the progression of the cell cycle,” Goel said. Her research position is making a difference and it allows her to gain tangible experience in a field she is passionate about.

The success stories are copious, and the opportunity that this platform has brought to prodigious students like these is without question.

At a billion-dollar research school, understanding where to begin can be intimidating. Muser alleviates these worries by connecting researchers and students through an accessible platform.
