Steve Brown's research interests include refrigeration and air conditioning, alternative refrigeration cycles, alternative refrigerants, organic Rankine cycles, alternative energy, thermodynamic modeling, two phase heat transfer, human thermal comfort modeling, and bio heat transfer. He is the recipient of the 2001 Ralph Teetor Educational Award from the Society of Automotive Engineers, was named a DuPont Young Professor Award recipient for the period 2001-2004, received the 2010 ASHRAE Journal Best Paper Award, was awarded the Provost Award for Overall Teaching in 2011, was elected an ASHRAE Fellow in 2013, received the International Journal of Refrigeration Best Paper Award for ones published in 2013/2014, and was honored the ASHRAE Distinguished Service Award in 2015. He serves as an ABET evaluator, is an Associate Editor of Science and Technology for the Built Environment (formely known as HVAC&R Research), and is active in ASEE, ASME, IIR, and ASHRAE, where he is a member of two technical committees. He is a registered professional engineer in the State of Maryland.
