Dr. Khalil’s research interests include green energy systems, environmental risk assessment, life cycle assessment (LCA) of composite materials, and waste heat harvesting technologies. Because of his specialized expertise in probabilistic risk assessment (PRA), Dr. Khalil extended the scope of his research interests to cover cyber and physical security vulnerability assessment of critical infrastructures.
Dr. Yehia Khalil joined Yale University as a faculty member in 1993 where he taught the core courses in the undergraduate chemical engineering and environmental engineering curricula at Yale School of Engineering & Applied Science (SEAS). As a Senior Research Scholar at Yale School of Forestry & Environmental Studies (F&ES), Dr. Khalil advised students’ research in the environmental management graduate degree program and taught graduate courses entitled Environmental Risk Assessment (ERA), Environmental Control Technologies (ECT). Dr. Khalil is also an affiliated faculty member at Yale Climate and Energy Institute (YCEI) and Yale College where he taught Green Energy Systems (GES) courses and was the champion of the online engineering courses at Yale College summer program. Before his teaching career at Yale University, Dr. Khalil was a Technical fellow at the Center for Advanced Engineering Studies at the Massachusetts Institute of Technology and taught nuclear risk assessment and nuclear reactors safety at MIT.
Dr. Khalil is the current Operating Agent of the Hydrogen Safety Task of the International Energy Agency (IEA), the editor-in-chief for the IEA Hydrogen Safety Journal, an editor of the Process Safety & Environmental Protection (PSEP) Journal, the European Federation of Chemical Engineering, Elsevier Publisher, and a senior editor of the Journal of Environmental Engineering & Ecological Science, Herbert Publications Ltd., Bedfordshire, UK.
Dr. Khalil is a recipient of several awards and scientific recognitions, among which is the Senior Moulton Medal from the Institution of Chemical Engineers (IChemE) in the United Kingdom, the Yale F. K. Weyerhaeuser Faculty Research Grant award, the Société Française D’énergie Nucléaire recognition plaque, the Shota Rustaveli National Science Foundation in Tbilisi, Georgia, the Chinese Nuclear Society (CNS), and the Japan Society of Mechanical Engineers (JSME). Dr Khalil is a recipient of Harvard University’s academic achievement award in sustainability. He is also a recipient of the American Institute of Chemical Engineers (AIChE) award for dedicated leadership as Yale Faculty Advisor for the AIChE Student Chapter. Dr. Khalil has six patents, patent applications, and filed over 100 invention disclosures in the engineering field.
Dr. Khalil earned Nucl. Eng. and M.S. degrees in Nuclear Engineering from the Massachusetts Institute of Technology (MIT), M.S.C.E.P in Chemical Engineering from MIT School of Chemical Engineering Practice, and M.S. in Management Science and Engineering from Stanford University, California, USA. Dr. Khalil earned a Master degree (MLA) in Sustainability and Environmental Management from Harvard University, Cambridge, Massachusetts, USA. He earned his Ph.D. in chemical engineering from the University of Connecticut at Storrs and Sc.D. in management science from the school of Management at University of New Haven in Connecticut, USA. He conducted post-doctoral research in chemical engineering at Yale School of Engineering & Applied Science and in management at Yale School of Management (SOM).
