About

Arny Leroy is a mechanical engineer who specializes in the design of mechanical systems. Arny is currently a Research Specialist Limited at the Device Research Laboratory at MIT under the supervision of Prof. Evelyn N. Wang. As part of his PhD work, Arny worked on passive radiative and evaporative cooling using novel polyethylene aerogels for passive cooling of buildings and refrigeration of food produce. Arny is currently working on designing, fabricating, and testing a micro combustor for a portable atmospheric water harvesting device that can extract potable drinking water from the ambient air. Arny's work is motivated by advancing the fields of thermal and energy sciences to make a more energy efficient and sustainable world.
