Salvador Barraza-Lopez currently is an Associate Professor at the Department of Physics at the University of Arkansas, where he began his career as faculty in the Fall of 2011. He obtained a PhD from the University of Illinois in 2006 under the guidance of Karl Hess. He completed postdoctoral stays at Virginia Tech and Georgia Tech, working with Kyunwgha Park and Mei-Yin Chou, respectively. He is the recipient of an Early Career Award from the DOE.
Research in the group revolves around two-dimensional atomic materials and charge transport across nano-structured materials. We maintain active relations with experimental and theoretical groups on campus and elsewhere.
The group interests are presently focused on theoretical and computational means to predict the properties of two-dimensional materials, and on quantum transport.
