Galit Lahav received her PhD in 2001 from the Department of Biology in the Technion, Israel Institute of Technology. Between the years 2001-2003, she completed her postdoctoral fellowship at the Weizmann Institute of Science in Israel. She carried out single-cell studies on the dynamics of proteins in living human cells, and used quantitative and computational techniques to model cellular responses. She then spent a year at Harvard’s Bauer Center for Genomics Research, and in the fall of 2004, was appointed as an Assistant Professor in the Department of Systems Biology at Harvard Medical School. Lahav discoveries emphasize the importance of developing new technologies to allow quantitative single-cell studies of protein and network behavior. Her lab combines experimental and theoretical approaches to study the dynamics of signaling networks and cellular decision-making in individual human cells.
