Susan T. Glassmeyer is a research chemist in the US Environmental Protection Agency's Office of Research Development, National Exposure Research Laboratory. Dr. Glassmeyer earned a B.S. in chemistry from Xavier University, and a M.S.E.S. degree in environmental chemistry and Ph.D. in environmental science from Indiana University. Dr. Glassmeyer's research is focused on contaminants of emerging concern (CECs) – both chemicals such as pharmaceuticals as well as microorganisms – in the water cycle. She has coordinated several projects examining the occurrence, fate and transport of CECs in wastewater, surface water, groundwater, and drinking water.
Originally from Edinboro, Pennsylvania, Dr. Tim Hoellein completed a B.S. in biology from West Virginia Wesleyan College and a Ph.D. in biology at the University of Notre Dame. He arrived at Loyola University Chicago in Fall 2010 after spending 2 years as an assistant professor in Baruch College, New York City. Dr. Hoellein's research focuses on water pollution including dissolved chemicals (i.e., nitrogen and phosphorus) and particulate material (i.e., microplastics and trash) in urban environments. He is interested in the ecology of pollution in aquatic ecosystems: how it is broken down and how it interacts with aquatic organisms. Dr. Hoellein's overarching goals for this research are to contribute to a greater understanding of the sources and solutions to a wide array of pollutants, to incorporate students and teaching into the work, and to communicate his results with other scientists and the general public. It's his hope this will lead to application of the research towards improved prevention and management strategies.
Barbara Mahler, Ph.D., P.G., is a research hydrologist at the USGS in Austin, TX, where she is a geochemist for the Regional Stream Quality Assessment team. Research by Dr. Mahler and her colleagues has been instrumental in identifying and quantifying the importance of coal-tar-based parking lot sealcoat as a source of PAHs at the national scale (tx.usgs.gov/sealcoat.html). Dr. Mahler's research includes evaluating contaminant sources, including rooftop runoff, suspended sediment in streams, contaminated runoff from parking lots, and house dust.
Stephanie Showalter Otts is the Director of the National Sea Grant Law Center and the Mississippi-Alabama Sea Grant Legal Program at the University of Mississippi School of Law.
