Greg Wagner received his Ph.D. in Mechanical Engineering from Northwestern University in 2001. He spent over 12 years as a staff member and later manager in the Thermal/Fluid Science and Engineering department at Sandia National Laboratories in Livermore, CA, where his work included multiscale and multi-physics computational methods, multiphase and particulate flow simulation, extended timescale methods for atomistic simulation, and large-scale engineering code development. In January 2015 he joined the faculty of the Mechanical Engineering department at Northwestern. His current research focuses on applying novel simulation methods and high performance computing to multiphase flows and flows with complex and moving geometries. He is the author or co-author of over 50 journal articles, and his awards include the Zienkiewicz Prize for Numerical Methods in Engineering. He is an associate editor for Computer Modeling in Engineering & Sciences and Journal of Micromechanics and Molecular Physics.
