Dr. Reza Sadr's research interests include experimental techniques in thermo/fluid science with a focus on advanced energy-efficient systems. He has active projects in nano/micro-fluids, droplets and sprays, alternative and bio fuels, atmospheric turbulence, and supercritical fluid flows. Upon joining Texas A&M, Dr. Sadr focused his attention on advanced energy-efficient systems on several fronts at the Qatar campus. He continued his work on micro/nano fluidics for bio applications and Brownian motion. He has initiated  active research on thermo-hydraulics of supercritical CO2 flows and potentials of CO2-hydrocarbon based refrigerants, with a recent support funded by Shell. He has also successfully worked with Rolls-Royce, German Aerospace Institute (DLR), and Shell Inc. for spray and combustion characterization of gas-to-liquid (GTL) fuel. He is continuing his work in studying Atmospheric Surface Layer (ASL) in Qatar to characterize pollution dispersion and potential wind energy applications in this region.
