Professor Papazian received her B.S. in Chemistry from the University of Michigan in 1977. She received her Ph.D. in Biological Chemistry from Harvard University in 1983. She was a postdoctoral fellow in Dr. Lily Jan’s laboratory at the University of California at San Francisco from 1983-1989. She joined the UCLA faculty in 1989 and now holds the rank of Professor in the Department of Physiology
