Thesis Advisor: Dan Kaufman, M.D., Ph.D.

Thesis Research: My work focuses on the development of lymphocytes from different populations of human stem cells. These include hematopoietic stem cells (HSCs) as well as human embryonic and induced pluripotent stem cells. Use of each of these starting populations provides a reliable in vitro system to study human lymphocyte development. In contrast to HSCs, the use of hESC- and iPSC-derived hematopoietic progenitors provides a genetically tractable system to study the molecular mechanisms driving human lymphocyte development into T, B, or NK cells.
