Dr. Charlene W. Bayer is the Chairman and Chief Science Officer at Hygieia Sciences LLC, founded to commercialize her technology for detecting human diseases from breath and her advanced indoor air quality research. She is the current chair of the ASHRAE TC2.3. She is a current member of the USGBC EQ TAG, as well as the past Vice Chair of the USGBC Research Committee, a member of the and IAQP pilot credit workgroup, and a Senior Research Fellow for Materials and Healthy Buildings at USGBC. She also is a member of the US General Services Administration Green Building Advisory Committee, serving as co-chair of the Green Leasing Task Group. She is a Principal Research Scientist Emeritus at the Georgia Tech Research Institute. Over the last 30+ years, her research has spanned the gamut of the indoor environment. she has led research programs investigating many aspects of the indoor environment, exposures, and health impacts, such as asthma exacerbation., such as building diagnostics; product emissions; contaminant sources identification and control; air cleaner technology development; strategic ventilation strategies; effects of airborne exposures on asthma and respiratory health; schools indoor air quality; real-time instrumentation development, methods development for airborne species; methodology development for measurement of gas-phase filtration removal efficiency; indoor air quality management plans development; and interfacing indoor air quality and energy efficiency. Her research is conducted for a wide variety of industrial and governmental sponsors much of this research being multi-university/partner research efforts. Her research team has investigated indoor environmental quality in more than 50 buildings and 30 schools. Her recent research is developing breath analysis as a method to detect the presence of breast and lung cancer and other health status states, and to measure personal body burdens as a result of environmental exposures. Dr. Bayer is the holder of multiple patents and is the author and presenter of more than 150 technical papers, including one of the co-authors of the National Academies of Science report, Green Schools: Attributes for Health and Learning. She holds a Ph.D. and M.S. from Emory University in and a B.S. from Baylor University in Chemistry.
