My research programs are focused on developing an understanding of advanced composite material systems for use in extreme environments. My first research program focuses on processing ultra-high temperature ceramic (UHTC) multilayer coatings for use as advanced thermal protection systems in next generation aerospace vehicles. My second research program focuses on developing bulk multifunctional high-temperature ceramic nanocomposites reinforced with single-walled carbon nanotubes for enhanced toughness in ceramics that also posses novel electrical and thermal properties over monolithic ceramic materials, which make them great thermal management materials, and electrical conductors at temperature. My third research program focuses on materials for solar and energy applications. In collaboration with Sandia National Laboratories we are developing advanced nanocomposites of iron oxide and zirconia for use as high temperature hydrogen generation materials. We also have interest in developing advanced solid-oxide fuel cell (SOFC) materials, especially glass sealant materials for more reliable SOFCs. The UofA and Sandia National Laboratories fund my current research programs at the University of Arizona.
