Michael Waring

Department Head
Civil, Architectural and Environmental Engineering


Michael joined Drexel in 2009, after completing his Ph.D. in an NSF IGERT program in Indoor Environmental Science and Engineering at the University of Texas at Austin. His research exists at the intersection of environmental and architectural engineering. It focuses on indoor air quality and exposure, indoor aerosol and chemical modeling, and sustainable buildings. He believes that making buildings function more effectively is imperative to solving many societal challenges. Michael has received the NSF CAREER Award, as well as the New Investigator Award from the American Society for Heating, Refrigeration, and Air-conditioning Engineers. He holds a B.A. in English and Economics, B.S. in Architectural Engineering, M.S. in Environmental and Water Resources Engineering, and a Ph.D. in Civil Engineering, all from the UT-Austin.
