Dr. Devesh Ranjan is an Associate Professor in the GWW School of Mechanical Engineering at Georgia Tech since July 2014. He was previously a director's research fellow at Los Alamos National Laboratory (2008) and Morris E Foster Assistant Professor in the Mechanical Engineering department at Texas A&M University (2009-2014). He earned a bachelor's degree from the NIT-Trichy (India) in 2003, and master's and Ph.D. degrees from the UW-Madison in 2005 and 2007 respectively, all in mechanical engineering. His research program focuses on the mixing of materials at extreme conditions, the physics of hydrodynamic instabilities, and advanced power conversion cycles. His research efforts can potentially lead to advances in a number of fields including, energy, environment and most pertinently, inertial confinement fusion devices. He is a recipient of National Science Foundation CAREER Award, US AFOSR Young Investigator Award and the DOE-Early Career Award. Dr. Ranjan was named J. Erskine Love Jr. Faculty Fellow in 2015.
