Estefan is an assistant professor in the Department of Civil and Environmental Engineering at the University of Michigan. He completed his PhD at UC Berkeley in Geosystems Engineering studying the propagation of earthquake surface fault rupture through granular media and the interaction of surface fault rupture with the built environment. For much of his research, he utilizes the discrete/distinct element method (DEM) with high performance computing. His current research interests are in earthquake surface fault rupture, granular systems, and the characterization of granular materials using advanced imaging and modeling techniques.
