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.
Her expertise includes photovoltaic (PV) system performance evaluation and module reliability analysis risk analysis, photovoltaic performance and degradation, energy efficiency, technical supervision of the installation of utility-scale PV research plants, and supervision of the activities for a new PV module testing laboratory. She has developed a probabilistic risk analysis study to assess technical, occupational, and environmental risks for the manufacturing process of crystalline silicon PV cells. Her current research focuses on understanding the mechanisms of failures of PV modules with the support of the X-ray material analysis capabilities offered by the National Synchrotron Light Source. Her expertise in PV started in 2003 working with the Joint Research Centre of the European Commission in close contact with technical analysis and the normative context of PV module qualification. She has a master’s degree in electric engineering from the Polytechnic University of Milan, Italy, and doctorate in energy risk and safety from Delft University of Technology in the Netherlands.
