Research Interests

Research interests include the study and computational modeling of contact between materials undergoing non-linear large deformations in continuum mechanics. More precisely, the research and development of Eulerian methods to model impact, fractures, interface bonding, erosion due to wear, thermal loading-shock, phase-transformations, and chemical reactions.
