Research interests:  Theory and modeling of energetic materials; First-principles simulation of compression and shock loading of solids; Fragmentation at high strain rates; Impact-resistant nanocomposites.        

Our current projects focus on novel energetic materials and structural composites. We are simulating organometallic nanostructures as possible routes to fast, kinetically-limited combustion of aluminum in propellants or explosives. We are studying the fragmentation behavior of reactive materials and similar composites being considered for next-generation warheads. In collaboration with several experimentalists, we are modeling interfacial interactions and mechanical response of nanostructured composites for lightweight armors.

Research interests centered on solid state materials. In particular, research efforts have been directed to engineer nanostructured and multifunctional materials.

Our group has developed novel synthetic pathways for materials preparation; instances of the same include reduction-expansion synthesis and plasma/aerosol methodologies. Special attention has been given to the characterization of the nanomaterial structural features and their correlation with observed properties and reactivity.

Application projects include the generation of thermally stable materials for batteries, catalysts, structural and high energy density materials.

Future areas of interest include the development of high temperature and impact resistant materials.
