This week Shelly Miller, PhD joins us to discuss some recent research and thoughts on weatherization, ventilation & respiration. We hear a lot that we need to tighten homes and ventilate them. What does that do with respect to occupant health? Today we will go over some results from work Dr. Miller has done. Dr. Miller is an Associate Professor at the University of Colorado Boulder in the Mechanical Engineering Department and faculty in the interdisciplinary undergraduate Environmental Engineering Program. At the University of Colorado Boulder Dr. Miller investigates indoor air quality, assesses exposures to air pollutants, and develops and evaluates air pollution control measures. Her research has included studying weatherization of homes and indoor air quality, understanding the role of ventilation systems in the transmission of infectious agents in buildings, engineering controls for reducing exposures to infectious diseases, studying ultraviolet germicidal coil cleaning technology, source apportionment of particulate matter and associated health effects, characterization of indoor air quality and the microbial communities in homes, and investigating urban air quality issues including industrial odor episodes. Dr. Miller has received funding for her research program from the US EPA, CDC, NIOSH, NSF, NIH, ASHRAE, HUD, Alfred P. Sloan Foundation, and various private foundations and industry sponsors.
