Susan M. Dymecki (born June 19, 1960) is an American geneticist and neuroscientist and director of the Biological and Biomedical Sciences PhD Program at Harvard University.[1] Dymecki is also a professor in the Department of Genetics and the principal investigator of the Dymecki Lab at Harvard. Her lab characterizes the development and function of unique populations of serotonergic neurons in the mouse brain. To enable this functional dissection, Dymecki has pioneered several transgenic tools for probing neural circuit development and function. Dymecki also competed internationally as an ice dancer, placing 7th in the 1980 U.S. Figure Skating Championships.[2][3][4]
