Dr. Shankar Subramaniam is Professor in the Department of Mechanical Engineering at Iowa State University and Founding Director of CoMFRE: Multiphase Flow Research and Education. He received his B. Tech. in aeronautical engineering from the Indian Institute of Technology, Bombay (Mumbai) in 1988 and is a recipient of the President’s Silver Medal. He earned his PhD at Cornell University, subsequent to an MS in Aerospace Engineering at the University of Notre Dame, USA. After his PhD he spent two years as a post-doctoral researcher at Los Alamos National Laboratory in the Theoretical Division’s Fluid Dynamics Group. Prior to joining the ISU faculty in 2002, Subramaniam was an assistant professor at Rutgers University. He is a recipient of the US Department of Energy’s Early Career Principal Investigator award. His areas of expertise are in theory, modeling and simulation of multiphase flows (including sprays, particle-laden flows, colloids and granular mixtures), turbulence, mixing, and reacting flows. His current research concerns direct numerical simulation of granular and gas-solid flows, bubbly flows, and hierarchical coarse-graining approaches. He has served on the editorial board of the journal Atomization and Sprays and International Journal of Spray and Combustion Dynamics.
