Professor Zok obtained his Ph.D. from McMaster University in 1989 and joined the faculty of UCSB in 1990. His research interests concern the mechanical and thermal properties of fiber-reinforced metal and ceramic matrix composites and the development and validation of material models. He is currently Associate Editor for the Journal of the American Ceramic Society and Section Editor (Ceramics, Composites and intergrowths) for Current Opinion in Solid State and Materials Science.
