Biography

Dr. Sagasti received his PhD from UCSF, where he worked with Cori Bargmann studying celll specification and left/right asymmetry in the nervous system of the nematode C. elegans. He began using zebrafish as a model at the Skirball Institute, NYU Medical Center as a post-doc with Alex Schier. In the summer of 2005 he was a Grass Foundation Fellow at the Marine Biological Labs in Woods Hole, Massachussetts. He began as a UCLA faculty member in the MCDB department in September 2005. His lab uses a combination of imaging, molecular, and genetic approaches in zebrafish to investigate on the morphogenesis of sensory axons and skin cells during development and repair.
