Professor of Mechanical and Environmental Engineering, University of Colorado Boulder

My current research projects include assessing and designing engineering controls such as filtration and ultraviolet germicidal irradiation for improving indoor environmental quality, reducing building energy consumption and improving health, source apportionment of PM2.5 and association with health effects, association of coarse particles with health effects in urban and rural areas, characterization of indoor environmental quality in homes, characterizing ultrafine particles that penetrate into mechanically ventilated buildings, understanding the microbiology of the built environment, studying how HVAC systems play a role in infectious disease transmission, and identifying sources of air toxics and noxious odors in urban communities. I have received funding for my research program from the US EPA, HUD, CDC, NIOSH, NSF, NIH, ASHRAE, Alfred P. Sloan Foundation, and various private foundations and industry sponsors.
