About me

Currently, I am working as a post-doctoral research associate in the Ray W. Herrick Laboratories at Purdue University. My research interests span broadly in areas of human exposure to extreme heat, water harvesting, adsorption chiller, multi-phase systems, wetting and texturing, interfacial dynamics, sustainable refrigeration and air conditioning, solar energy systems, and thermal management of engineering systems.
