H. Ezzat Khalifa
NYSTAR Distinguished Professor
Mechanical & Aerospace Engineering
Ph.D. in Engineering (Thermo & Fluid Dynamics) from Brown University.
Professor Khalifa is NYSTAR Distinguished Professor of Mechanical & Aerospace Engineering, and founding Director of the multi-institutional STAR Center for Environmental Quality Systems at Syracuse University. His distinguished career spans over five decades of academic and industrial experience in engineering teaching, research, technology & product development, and R&D planning and execution. He joined Syracuse University in 2001, after a 23-year career as a researcher, manager and R&D Director at United Technologies Corporation, where he was responsible for the development of a wide range of environmental control and energy conversion technologies and products. He served as the Director of Engineering of Carrier’s Carlyle Compressor Division from 1991 to 1998 and the Director of the Carrier R&D program at United Technologies Research Center before retiring to join Syracuse University in 2001. He is author and coauthor of more than 120 papers and 9 patents, and coeditor and coauthor of “A sourcebook on the production of electricity from geothermal energy.”
Professor Khalifa is the founding director of the STAR Center for Environmental Quality Systems, the academic research arm of the Syracuse Center of Excellence in Environmental and Energy Systems. He is also the originator of the SU Green Data Center power and cooling infrastructure concept and conducts research on data center energy efficiency there.
His research is currently focused on the experimental and analytical investigation and development of innovative distributed personalized environmental control systems; investigation of air, energy and contaminant transport in the personal microenvironment; intelligent distributed energy-efficient control of the indoor environment; analytical and computational studies of dust resuspension due to falling objects; development of reduced order models of air, energy and contaminant flows in the indoor environment; and development of innovative cooling and energy supply systems for high-efficiency data centers. He is currently the PI of over $4M of research projects funded by the US DOE and the State of New York, focused on research in micro-environmental control systems for local thermal management.
