Rate My Professor Roby Greenwald

Roby Greenwald is an Associate Professor in the Department of Population Health Sciences at the Georgia State University School of Public Health, a position he has held since joining the faculty in fall 2014. He directs the school's MPH program and Graduate Certificate in Public Health program, and was named interim Chair of the Department of Population Health Sciences in 2024. His primary research interests center on measuring the influences of air pollution on human health, with a focus on developing unique sampling systems to assess exposure in special microenvironments, such as inside vehicles during commuting. Greenwald's work also examines air pollution's effects on athletes' health, particulate matter reduction by roadside vegetation, and biomarkers of airway inflammation.

Greenwald holds a Ph.D. (2005) and M.S. (2001) from the Georgia Institute of Technology, and a B.S. (1994) in civil engineering from Clemson University. His career includes research faculty positions in the Department of Environmental Health at Emory University (2009-2014), where he contributed to studies on on-roadway exposure to particulate matter, and a postdoctoral fellowship in Emory's Department of Pediatrics (2005-2008), investigating air pollution exposure in pediatric asthma patients. During his doctoral studies at Georgia Tech (1999-2005), he developed an instrument for real-time measurement of water-insoluble aerosols and modeled atmospheric particulate matter's impact on crop production. Prior to graduate school, Greenwald served as a Peace Corps Volunteer in Benin, West Africa (1995-1998), teaching beekeeping. Key publications include 'A novel method for quantifying the inhaled dose of air pollutants based on heart rate, breathing rate and forced vital capacity' (PLOS ONE, 2016), 'On-roadway in-cabin exposure to particulate matter: measurement results using both continuous and time-integrated sampling approaches' (Aerosol Science & Technology, 2014), 'Associations between source-indicative pollution metrics and increases in pulmonary inflammation and reduced lung function in a panel of asthmatic children' (Air Quality, Atmosphere & Health, 2013), 'Breath formate is a marker of S-nitrosothiol depletion in severe asthma' (PLoS ONE, 2010), and 'Ionic determinants of exhaled breath condensate pH before and after exercise in adolescent athletes' (Pediatric Pulmonology, 2009).
