Dr. Albert Presto is an Assistant Research Professor in the Department of Mechanical Engineering, beginning in July 2012. He is also a member of CMU's Center for Atmospheric Particle Studies (CAPS). Dr. Presto joined the department after two years as a post-doctoral fellow at the National Energy Technology Laboratory and five years as Laboratory Manager and Research Scientist in CAPS.
Dr. Presto's research focuses on pollutant emissions from energy extraction and consumption and the subsequent atmospheric transformations that these emissions undergo. Energy consumption is a major source of pollutants to the atmosphere. Cars and trucks operating on gasoline and diesel fuels emit carbon monoxide, nitrogen oxides, and particulate matter. Particulate matter from mobile sources is largely the result of incomplete or inefficient combustion in the form of organic aerosol and black carbon. In addition to the direct emissions of pollutants, dilute exhaust undergoes oxidation in the atmosphere. This oxidation chemistry can lead to the production of secondary pollutants, such as ozone and secondary particulate matter.
Dr. Presto investigates the contributions of primary and secondary pollution with ambient measurements, laboratory experiments, source testing of pollution sources, and atmospheric models. This multi-pronged and multi-disciplinary approach allows for a holistic view of pollutant emissions and transformations in the atmosphere.
In addition to having environmental impacts, these pollutants, particularly ozone and particulate matter, adversely impact human health. Dr. Presto is collaborating with medical professionals to develop detailed studies of pollutant exposure on a neighborhood-by-neighborhood basis, and to better understand the relationships between pollutant emissions and adverse health effects such as childhood asthma.
