His research focuses on experimental and analytical studies to improve the energy performance of building envelopes, equipment, and systems. Some of his recent work at Oak Ridge National Laboratory includes energy efficiency enhancement of Army huts, thermal performance evaluation of various radiant barrier systems, lifetime energy and environmental impact of building insulation materials, identify and evaluate performance of lower-global warming potential alternative refrigerants for various applications and operating conditions, study suitability of procedures for evaluating performance of appliances and heating, ventilation, and air conditioning systems, and performance evaluation of thermochromic and electrochromic paints for buildings applications. He is also developing web-based energy-savings calculation to estimate energy and cost savings potential from improving building envelope airtightness. He earned a master’s and doctorate in mechanical engineering from Iowa State University. He is an American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) certified Building Energy Modeling Professional (BEMP) and member of ASHRAE, American Society of Mechanical Engineers (ASME), and Tau Beta Pi.
