Research Interests

My laboratory is interested in using genetic and molecular approaches in C. elegans to study nervous system development. We are interested in gaining new insight into molecular mechanisms involved in the establishment of neuronal cell morphology and, at a larger scale, in the morphogenesis of the ventral nerve cord in C. elegans.

Brief Biography

Dr. Colavita completed a Ph.D. at the University of Toronto with Joseph Culotti studying the Netrin axon guidance pathway. He then pursued postdoctoral research at Stanford University with Marc Tessier-Lavigne to study molecular mechanisms involved in axon branching.
