BiographyJohn Colicelli is a cell biologist and biochemist. He joined the Department of Biological Chemistry in the UCLA School of Medicine in 1990. He became a full professor in 2003. Dr. Colicelli earned his B.A. in Chemistry at Rutgers University and his M.S. and Ph.D. in Biochemistry from Columbia University in New York. He was a postdoctoral fellow at Cold Spring Harbor Laboratory. Dr. Colicelli's research is focused on molecular signal transduction in cancer biology and neuronal plasticity. He teaches cell biology at the graduate and undergraduate levels. Dr. Colicelli serves as a Departmental Vice Chair and as a member of the School of Medicine Faculty Executive Committee.
