Dr. Sophia Liu is a Core Faculty Member and Early Independence Fellow at the Ragon Institute of Mass General, MIT, and Harvard. She enjoys creating new ways to measure temporally and spatially dynamic cell interactions and is particularly interested in studying T- and B-cell development. Her lab’s research focuses on immune cell interactions in tissues and dynamics across immune development and aging. She talks about the spatial mapping of T-cell receptors, what happens to the thymus during aging, and her experience starting a lab straight out of her PhD!
