Our research is in the areas of thermo-fluids and interfacial transport phenomena. We design and conduct experiments that reveal the fundamental dynamics of a vast array of interface-driven multiphase processes, over a wide range of time- and length-scales. From droplet microfluidics to environmental flows, from gas separation to alternative water resources, and from electronics cooling to turbomachinery aero-thermodynamics. The focus is on understanding the related flow and transport physics (mass, momentum, energy) at various application scales, and employing this knowledge for the development of sustainable and energy efficient solutions for industrial processes and aviation. To achieve this, we develop and employ a variety of optical flow diagnostics and thermophysical measurement techniques.
