Why I Chose the Tufts PhD in Immunology Program: Kimberly Carroll

Choosing a graduate program is a deeply personal decision, often guided by academic interests, future career goals, and the type of community that will shape your development as a scientist. To help prospective students get a better sense of what it’s like to be part of the Tufts Graduate School of Biomedical Sciences, we spoke with Kimberly Carroll, a current PhD student in the Immunology program. Below, Kimberly shares her experience at Tufts—from research to community life—and offers insights for those considering the program.

Why did you choose to pursue a PhD in Immunology?

"I’ve always been drawn to independent scientific thinking and asking complex questions. Immunology offers a fascinating space where curiosity meets real-world impact—especially since the immune system is so central to many diseases. What really sparked my interest was how inflammation, in particular, is not just a symptom but often a key driver of disease. Studying immunology felt like the best way to combine deep scientific inquiry with research that can directly improve human health."

What made you choose Tufts for your graduate studies?

"Tufts stood out because of how closely the Immunology program is connected to the hospital setting. Through the MERGE-Inflammation program, I got to see how inflammation affects real patients, which grounded my research interests in a tangible way. On top of that, Tufts struck a rare balance between academic rigor and a genuinely warm, supportive environment. From the start, it felt like a place where I could grow both professionally and personally."

What is the focus of your research?

"I study a unique subset of B cells—cells that most people associate with producing antibodies. But the B cells I focus on develop in unexpected tissue sites and have roles beyond traditional immunity. I’m exploring how these cells help regulate inflammation to support healthy tissue development in early life. This could open new pathways to treat inflammatory diseases and improve organ health. It's exciting to uncover the immune system’s broader role in maintaining tissue balance and development."

How has your experience been in the program so far?

"It’s been incredibly rewarding. The program really fosters independence—you’re encouraged to take ownership of your research—but there’s also a strong emphasis on collaboration. I’ve built meaningful relationships with faculty at Tufts and beyond, which has helped advance both my research and career development. I’ve grown a lot in terms of problem-solving, initiative, and scientific communication."

What’s your favorite aspect of the Immunology program?

"Definitely the close-knit community. The smaller size means you really get to know your peers and mentors. It’s easier to have meaningful discussions, get feedback on your work, and feel supported. That sense of connection has made a big difference in my graduate experience."

What do you enjoy outside of the lab?

"I’m an avid runner and love exploring the scenic trails around Boston. I also spend a lot of time with friends and family—whether we’re running, biking, or just enjoying good food together. It’s important to have that balance, and Boston offers a great backdrop for both work and relaxation."

What has been your proudest accomplishment at Tufts?

"Receiving an F31 fellowship was a big moment for me—it was unexpected and has been a great support for my research. I’ve also had the chance to present at a few international conferences, which has been a fantastic learning experience, especially this early in my career."

What are your goals after graduation?

"I hope that my research contributes meaningfully to the field of biomedical science—not just through publications, but by opening up new directions for others to explore. I’d love to know that my work helped move the field forward, even in a small way."

What would you like prospective students to know about Tufts GSBS?

"Tufts is a welcoming, collaborative place that encourages scientific independence while offering plenty of support. It’s academically challenging, but also nurturing—which makes it a great environment to grow as a researcher and as a person."
