Background

Dr. Garimella began at Tech in August 2003 as an Associate Professor and Director of the Sustainable Thermal Systems Laboratory. Prior, he was an Associate Professor at Iowa State University, an Assistant and Associate Professor at Western Michigan University, a Research Scientist at Battelle Memorial Institute, and a Senior Engineer at General Motors.

Research

Dr. Garimella conducts research in the area of sustainable energy systems, such as absorption and vapor compression heat pumps, natural refrigerant space-conditioning systems, and automotive climate control/propulsion cooling systems. His research also includes phase-change in micochannel and compact heat exchangers, heat and mass transfer in binary mixtures, and supercritical/transcritical fluid flow and heat transfer.
