He received a doctorate in computer science at the University of Tennessee in 2009, master’s in computer systems and software design, and his bachelor’s with a double major in computer science and mathematics with physics from Jacksonville State University. His research spans government-scale database and management systems, graphical user interface design, medical software used for surgery, gesture recognition, graph-theoretic analysis, optimization, automation, systems genetic research, magnetic resonance imaging, image processing, artificial intelligence, supercomputing, and energy-efficient buildings. He currently serves at Oak Ridge National Laboratory’s Building Technologies Research & Integration Center (BTRIC) as a subprogram manager for software tools and models with oversight of projects, involving websites, web services, databases, simulation engine development, visual analytics, supercomputing, and artificial intelligence. He has lead creation of the world’s most accurate method for calibrating a simulation model to measured data, fastest building model creator, fastest buildings simulator, and largest archive of simulated building data. He is a joint faculty member at the University of Tennessee’s Electrical Engineering and Computer Science Department, and an active member of American Society of Heating, Refrigerating and Air-Conditioning Engineers and Institute of Electrical and Electronics Engineers.
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.
