Duane Wesemann, M.D., Ph.D.

Founder

Associate Professor of Medicine, Harvard Medical School

Associate Physician, Brigham and Women's Hospital


From: Rocky Mountains, USA

Duane worked odd jobs throughout high school, including paper boy, dishwasher, janitor, wallpaperer, mailbox painter, and ring resizer to pay for flying lessons. He was turned on to biology from a young age and received his M.D. and Ph.D. with Tika Benveniste studying cell biology and learned B cell biology from Max Cooper and Fred Alt.

Anna Romanov, Ph.D.

Joined 2025

Ph.D. Biological Engineering, Massachusetts Institute of Technology, 2025

B.S. Biomedical Engineering, Georgia Institute of Technology, 2020


From: Atlanta, Georgia

Anna grew up in Georgia before moving to Boston for her PhD at MIT, where she engineered virus-like nanoparticles from DNA origami to probe how nanoscale antigen organization shapes immune responses to vaccination. Along the way, she fell in love with the strange and beautiful world of germinal centers, the hubs where B cells evolve and refine antibodies. In her postdoc, she aims to combine bioengineering creativity with deep immunology to uncover the rules of antibody evolution and germinal center biology, and to explore how they can be harnessed in vaccinology and autoimmunity. Outside the lab, Anna enjoys exploring Boston’s art scene, playing violin, baking bread and desserts, and traveling. She believes that good science, like good bread, requires patience, curiosity, and just the right amount of structure.

Sweta Khobragade

Joined 2023

Lab Manager, Senior Research Lab Technician

M.Sc. in Biotechnology


From: Mumbai, India

Sweta completed her M.Sc. in Biotechnology, where she developed a fascination for the vast scientific world out there. As a research fellow at NCCS, Pune, India, she studied the apoptotic (cell death) pathway in the Leishmania parasite, which causes leishmaniasis. She also collaborated on proteogenomic studies of Leishmania. Her interest in the immunological aspect of infection biology led her to research the Complement biology (innate arm) of the immune system, using the viral complement regulator Kaposica of the KSHV virus. To further explore the adaptive arm of immunology, she then joined the Wesemann lab. Where she is currently studying B cell evolution for de novo recognitions also investigating the HIV-1 Env protein for immunogen design. Sweta also manages the lab’s inventory, mice facility, and general maintenance.
