Dr. Desiderio Kovar earned his Ph.D. in materials science and engineering from Carnegie Mellon University in 1995. He joined the faculty in the Department of Mechanical Engineering at The University of Texas at Austin in 1997 after completing post-docotoral training at the University of Michigan. He is affiliated with the Texas Materials Institute and the Center for Nano and Molecular Science and Technology. Dr. Kovar's areas of study involve microstructure/property relationships in ceramics, metals, and composites. He has studied the influence of grain size, grain shape, and grain size distribution on the fracture resistance and mechanical reliability of toughened ceramics. At the University of Texas at Austin, he developed a lower cost method for fabricating bulk, highly textured alumina ceramics and studied the influence of texture on fracture resistance of this material. He has also studied the fracture resistance and high temperature mechanical behavior of laminates and other low-cost ceramic composites. His current research interests center around processing/microstructure/property relationships in nanostructured metals and ceramics and on processing strategies for producing microarchitectured honeycomb ceramics with tailored properties.
