Roby Greenwald

Assistant Professor    

Ph.D., 2005, Georgia Institute of Technology
M.S., 2001, Georgia Institute of Technology
B.S., 1994, Clemson University


Roby Greenwald is an assistant professor in the Division of Environmental Health at the School of Public Health where he joined the faculty in fall 2014.

His primary research interests are measuring the ways in which air pollution influences human health, and much of his work involves the development of unique sampling systems for assessing exposure to air pollution in special microenvironments such as inside vehicles while commuting.

From 2009-2014, He was on the research faculty of the Department of Environmental Health at Emory University. From 2005 to 2008, He was a post-doctoral fellow in Emory’s Department of Pediatrics and worked on a project investigating the influence of air pollution exposure on pediatric asthma patients. From 1999-2005, He was a PhD student at Georgia Tech and worked on two projects: development of an instrument to measure water-insoluble aerosols in real-time and computer modeling of the influence of atmospheric particulate matter on crop production.

Prior to graduate school, He taught beekeeping as a Peace Corps Volunteer in Benin, West Africa (1995-1998) and studied civil engineering at Clemson University (1990-1994).
