S. Lawrence Zipursky is an American neuroscientist and molecular biologist known for his contributions to the study of neural circuit development, particularly in the model organism Drosophila melanogaster (fruit fly). He holds a professorship in the Department of Molecular and Cellular Biology at Harvard University and is an investigator with the Howard Hughes Medical Institute (HHMI).
Education and Academic Career
Zipursky earned his doctoral degree in biology from Harvard University, where he conducted research on cell adhesion molecules. Following his Ph.D., he completed postdoctoral training in neurobiology before joining the faculty at Harvard University. Over the course of his career, he has risen to the rank of Professor and has served in various leadership roles within the university’s research community.
Research Focus
Zipursky’s research centers on the molecular mechanisms that guide the formation and specificity of synaptic connections in the nervous system. His work has elucidated the role of the immunoglobulin superfamily of cell adhesion proteins in directing the targeting of neuronal processes and establishing precise neural circuitry. Notable achievements include the identification of the Drosophila protein Dscam (Down syndrome cell adhesion molecule) as a key player in self‑avoidance and synaptic specificity.
