About

Andy May is an Assistant Professor in the Department of Civil, Environmental, and Geodetic Engineering in the College of Engineering at The Ohio State University. He is also an Associate Fellow of the Ohio State Center for Automotive Research and is one of the Affiliated Faculty with the Ohio State Environmental Science Graduate Program. He holds a BE in Chemical Engineering from the University of Delaware, an MS in Civil and Environmental Engineering from Clarkson University and a PhD in Mechanical Engineering from Carnegie Mellon University. Prior to his arrival at Ohio State, he was a post-doctoral scholar in the Department of Atmospheric Science at Colorado State University.

May’s main research focus is the atmospheric impacts of combustion emissions. Activities range from comprehensive source characterization to the utilization of low-cost sensors for monitoring urban air quality. Currently funded projects include an inter-comparison of black carbon instrumentation relating to open biomass burning emissions, an investigation of engine restart emissions from vehicles with idle-reduction technologies, and the use of low-cost sensors for monitoring traffic-related pollution in urban environments.
