In this episode, we sit down with Professor Meredith Niles to explore how climate-friendly agriculture—from methane-reducing rice irrigation to no-till farming—is actually a quiet powerhouse for public health. While traditional environmental messaging has hit a wall, shifting the narrative to human health benefits (like keeping heavy metals out of baby food and clearing our air) might be the key to finally getting farmers, consumers and policymakers on board. It’s time to take off the carbon goggles and look at the health potential of sustainable farming.

More than 6.5 million people are expected to attend the World Cup this summer at stadiums across Canada, the U.S. and Mexico. One of the largest sporting events in world history, the tournament is presenting unique infectious disease challenges for public health officials. To help, spatial epidemiologist Professor Will Goedel has developed an interactive map to track the movements of World Cup teams and their fans. He explains how his live-updated tracking map is helping health departments, and how it might be able to prevent a disease outbreak before one starts.

Meat is on the top, grains are at the bottom, scientists are concerned. Nutrition expert Jennifer Sacheck deconstructs the controversial new food pyramid, what it means for your health—and your wallet. She breaks down the new dietary guidelines, how much protein Americans actually need and how the beef lobby may be reshaping everything from SNAP benefits to cafeteria trays.

When you check the weather on your phone, you're getting a "best guess" based on the nearest airport—but your actual neighborhood could be much hotter. And in high-risk communities, this invisible temperature spike or major air quality issue transforms a daily forecast into a serious medical emergency. In this special episode in honor of Brown’s first-ever Climate Week, environmental epidemiologist Allan Just explains how his team uses NASA satellite data to measure hyper-local temperatures and air pollution. Discover why these precise measurements are vital for public health, especially for those on common medications that can unexpectedly increase vulnerability to extreme heat.

What does it take to lead a top-tier School of Public Health? For Dr. Francesca Beaudoin, the journey started in the chaos of the ER. In this episode of Humans in Public Health , we sit down with Interim Dean Beaudoin to trace an incredible trajectory. She has experienced Brown from every possible angle: first as a medical resident, then a doctoral student, then as member of the faculty, a department chair and administrative leader. Now she steps into the role of Interim Dean, prepared to propel the school forward with momentum. Host Megan Hall sits down with Dr. Beaudoin to discuss how 20 years in academia and on the medical frontlines—from treating acute trauma to staffing mobile opioid recovery units—prepared her to lead during a time of transition.

In this episode, host Megan Hall sits down with the co-directors of Brown University’s new AIM Lab, emergency physician Dara Kass and legal expert Liz Tobin-Tyler , to discuss the chaotic intersection of medicine and law three years after the Dobbs decision. As state abortion bans create a "chilling effect" that leaves clinicians paralyzed by legal fear, the AIM Lab is stepping in to provide a practical roadmap for emergency care and maternal health. Kass and Tobin-Tyler share how they are moving past the political noise to solve the public health crises on the ground, offering a harm reduction approach that protects both doctors and patients while training a new generation of advocates to value the lives of pregnant people in every state.

A quarter of young adults are turning to AI chatbots like ChatGPT for mental health advice, highlighting a massive shift in how people seek support. Dr. Ateev Mehrotra discusses his research and the urgent need to balance AI's capacity for providing accessible, cost-effective care with its potential to unwittingly cause harm.

In a world teeming with health data—from smart watch accelerometry to millions of hospital system electronic records—how do researchers find out which medical treatments truly work? Biostatistician Rebecca Hubbard discusses the messiness of real-world data, the limits of randomized control trials and how both of these powerful—but imperfect—methods are essential for building trustworthy evidence in public health.

Measles has been declared eliminated in the U.S. for 25 years, but a surge in cases is threatening that status. Jennifer Nuzzo, director of the Pandemic Center at Brown University, joined Humans in Public Health to break down the outbreak, the chaotic federal response and how her team's tracker is stepping in to provide reliable, life-saving data.

We all understand the power a song can have to recall vivid memories, seemingly sending us back in time. Professor Ellen McCreedy is a musician whose gerontology research harnesses music’s power to recall memories. She’s testing an intervention that brings personalized music playlists to nursing homes in order to help ease dementia symptoms for patients, without using medication. Driven to give dementia sufferers—and their caregivers—moments of having themselves back again, McCreedy joined Humans in Public Health to discuss her work, its challenges and the grandmother who originally inspired her.

Since the 1980s, the U.S. has experimented with various forms of managed health care. But none of them has managed to control costs or improve health outcomes, argues Senior Fellow Hayden Rooke-Ley. In this episode of Humans in Public Health, he explains a radical new idea from CAHPR researchers for delivering lower health care costs that is actually quite old-fashioned: a return to fee-for-service.

They’re not just in your nail polish. Per- and polyfluoroalkyl chemicals are everywhere—in our homes, clothing, the personal care products we use, and in our bodies. Postdoctoral researcher Amber Hall explains the dangers PFAS pose, especially to developing humans, and helps us learn how to avoid them. The burden of protecting our children’s health from toxic chemicals, she argues in the latest episode of Humans in Public Health, shouldn’t be borne by individuals. Regulation, Hall says, is needed to push through product-level change and protect the public’s health.
