"As Professor of Ceramic Engineering and Director of the Colorado Center for Advanced Ceramics, I teach and manage research in ceramics processing and properties. Much of my research focuses on mechanical behavior of complex material systems that go into applications such as advanced jet engines, solid oxide fuel cells, thin films and protective armor. Specific projects focus on lithium aluminum silicates, transparent ceramics, thin films, functionally graded composites, and bimaterial interfaces. My research group examines the relationships between processing and fracture and deformation of these materials through a combination of numerical simulation and experiments. We are also engaged in a variety of advanced ceramic processing activities.

Before coming to CSM, I worked at Los Alamos National Laboratory on fundamental studies of the deformation and fracture of ceramic composites for use at very high temperatures, as well as the design of armor systems for the U.S. Air Force. Prior to Los Alamos, I spent a year at the Max Planck Institute in Stuttgart, Germany, working on processing and properties of metal/ceramic interfaces.

My current funding sponsors include Department of Energy's Office of Basic Energy Sciences; National Science Foundation; Army Research Office; Department of Energy, NETL; CoorsTek, Incorporated; Corning, Incorporated."
