Materials science, design of materials for high-temperature structures, modeling and testing of thermal, mechanical and environmental responses, processing/properties of ceramics and ceramic composites, oxide materials for battery applications
Current interests include fiber-reinforced ceramic composites, which offer extremely high strength-to-weight ratio at high temperatures, making them critical for a wide range of aerospace and power generation systems (e.g., gas turbine engines, hypersonic flight and thermal protection). These composites have complex and heterogeneous microstructures, leading to highly anisotropic mechanical and thermal properties. We aim to understand how to process these materials, how to optimize their microstructures for a particular application, and how to measure and predict their behavior in extreme mechanical, thermal and environmental conditions. Activities include analysis of system performance, design of composite microstructures, development of new material systems, and advanced testing and modeling to understand damage and lifetime.
Other research topics have included fracture phenomena, strengthening, toughening, environmental stability and reliability of advanced structural materials, with emphasis on ceramic and intermetallic matrix composites, ultra-hard materials (cBN), transformation-toughened materials and monolithic ceramics.
