Richard Hennig

Richard Hennig received his Diploma in physics at the University of Göttingen in 1997 and his Ph.D. degree in physics from Washington University in St. Louis in 2000. After working as a postdoctoral researcher and research scientist at Ohio State University, he joined the faculty of the Department of Materials Science and Engineering at Cornell in 2006. Professor Hennig’s research in computational materials science focuses on atomistic studies of defects, phase transitions, electronic properties, and mechanical behavior of materials. He aims to develop computational techniques that both accurately predict materials properties and provide an estimate of their accuracy and to apply these methods to accelerated materials development and enhanced understanding of the effect of atomic-scale processes on meso- and macroscale behaviors. His strengths are atomic multiscale simulations that combine highly accurate quantum mechanical methods such as density functional theory and quantum Monte Carlo with efficient molecular dynamics simulations and saddle-point techniques.
