We are excited to welcome Caroline Sokol, MD, PhD, to the Ragon Institute as a new faculty member!

A physician-scientist and leader in allergy and immunology, Sokol studies how the immune system recognizes and responds to allergens, with the goal of developing new therapies to treat and prevent allergic disease. Her lab investigates the neuroimmune circuits underlying allergic disease, with a focus on how sensory neurons detect environmental allergens and coordinate immune responses.

At the Ragon, Sokol will lead the Sokol Lab while also serving as an Assistant Physician at Massachusetts General Hospital and an Assistant Professor of Medicine at Harvard Medical School.

Please join us in welcoming Dr. Sokol to the Ragon community.

The Ragon PRISM Science Club is back for 2026!

PRISM (Program of Ragon and IMES in Science and Medicine) is our outreach program for high school students from underrepresented communities in the Greater Boston area, meeting on Saturdays in March and April for 8 weeks.

The program, launched in 2022, is a joint effort between the Ragon Institute, MIT's Institute for Medical Engineering and Science (IMES), and the Harvard-MIT Program in Health Sciences and Technology (HST), housed at IMES. Each week features a different program, with a talk, discussion, and an activity facilitated by graduate students from IMES/HST and Ragon researchers.

Pictured is this year's cohort with Ragon founding director Bruce Walker, MD, on the grand staircase in the Ragon lobby. We are delighted to welcome these students and grateful for all of our collaborators on this program.

A new study from the Ghebremichael Lab at the Ragon Institute, published in the Biometrical Journal, introduces a statistical method that evaluates biologically linked outcomes jointly rather than relying on separate analyses that ignore their interdependence. The researchers demonstrated their methodology using data from a longitudinal pediatric HIV study examining the efficacy of antiretroviral therapy (ART).

This work provides researchers and clinicians with a new statistical framework and accompanying software tool for evaluating correlated outcomes. Although HIV data was used in this study, the method and software are broadly applicable to any setting involving interconnected outcomes.

A new study from the Balazs Lab at the Ragon Institute, published in Immunity, demonstrates that HIV escapes broadly neutralizing antibodies (bNAbs) through a limited set of conserved mutation paths, and that manipulating the cost of those paths can dramatically improve therapeutic outcomes.

"By studying the mutations the virus makes during selection by these antibodies, we find that the ease or difficulty of escape paths available to the virus are the real drivers of success or failure during treatment,” said principal investigator and corresponding author Alejandro Balazs, PhD.

“We believe this insight will be crucial for the development of future HIV therapies that employ combinations of antibodies that can exert orthogonal selective pressure on the virus to produce the check-mate conditions needed to continuously suppress HIV as a functional cure".

"I don't have a clue why I'm here." "Well, I really don't have a clue why you're here either."

Sometimes the most meaningful partnerships begin with the most unlikely introductions. When Ragon Institute Founding Director Bruce Walker, MD, met entrepeneur and philanthropist Phillip 'Terry' Ragon, neither knew why they'd been brought together. But a shared trip to South Africa, where Terry witnessed firsthand how HIV had overwhelmed hospitals and communities, changed everything.

Terry asked Bruce a simple question: What would it take to solve this? Bruce's answer: bring together the best minds at Harvard, MIT, and Mass General to make an HIV vaccine. Terry's response was to commit the funding to make it happen.

That conversation became the Ragon Institute, built on the belief that collaboration across disciplines could tackle one of humanity's greatest health challenges.

Watch Bruce and Terry share the story of how it all began. 🎥

A multi-institutional study published in Science Immunology, led by the Batista Lab at the Ragon Institute, in collaboration with researchers at University of Pennsylvania, Scripps Research Institute, Columbia University, MIT, and others, demonstrates that a single immunization can rapidly generate antibodies capable of neutralizing a broad range of HIV strains, thereby offering a potential path toward simpler HIV vaccine regimens.

A collaborative study published in Immunity from the Batista Lab and Liu Lab at the Ragon Institute, together with the Schief Lab at Scripps Research Institute, has uncovered a previously unrecognized mechanism that shapes how immune cells are selected during an immune response.

The team found B cells that bound the target most strongly actually spent less time in germinal centers than weaker-binding cells. And while B cells of similar strength could coexist without affecting each other, stronger-binding cells actively suppressed weaker ones targeting the same site.

"When we started examining this response, it became clear that the effect was highly localized, anatomically,” first author and Batista Lab research scientist Yu Yan, PhD, said. “We were able to identify cells in and around the germinal centers producing antibodies creating a hyperlocal feedback loop.”

"I came to college, two duffel bags, showed up at Kendall Square being like, I'm gonna make computer games…"

Sometimes the most impactful scientific careers start with unexpected turns. Bryan Bryson, PhD, arrived at MIT with a plan in mind, but instead found a completely different passion for understanding the fundamental ways our bodies fight disease.

Today, Bryson is an Associate Professor of Biological Engineering at MIT and a Ragon Institute core faculty member. His lab tackles one of humanity's oldest killers: tuberculosis. By combining immunology, bioengineering, and systems biology, his team is working to understand how immune cells control and eliminate pathogens—research that could transform how we develop vaccines for infectious diseases that have plagued humanity for centuries.

Watch to hear Bryson share his journey to becoming an immunologist at the Ragon.

After two weeks across Johannesburg, Durban, and rural KwaZulu-Natal, our 'Evolution of an Epidemic' course has concluded and our MIT and ALA students have returned home safely.

The course offered students a deeply meaningful learning experience, witnessing firsthand the realities of the HIV/AIDS epidemic in South Africa and the vital work being done by local communities and international partners like the Ragon Institute.

In the final days of the trip, students ventured into the rural areas of KwaZulu-Natal. Highlights included:

— Visiting the BabyCure program at Queen Nandi Hospital in Empangeni, where students met with mothers and learned how access to pre- and post-natal care is transforming lives while advancing HIV research.

— Exploring the African Health Research Institute's Somkhele campus, where students heard from local researchers and presented their own 'Shark Tank'-style pitches addressing pressing public health challenges.

— An early morning hippo and crocodile tour on the St. Lucia Estuary, followed by incredible game drives in the Hluhluwe-iMfolozi Game Reserve—including the chance to see the Big Five up close.

— Presenting their final group projects, synthesizing everything they learned over the course of the trip.

The students returned home this past Monday, and we are deeply grateful for their participation. This year's cohort brought enthusiasm, curiosity, and dedication to every moment, and we were honored to share another year of 'Evolution of an Epidemic' with them.
