IHSS&IWA26 / BRNO / CZECHIA / August 23–28, 2026 PROGRAMME BOOKLET 20 Kristopher McNeill Short CV: Kristopher McNeill is the Professor for Environmental Chemistry at ETH Zurich, where he and his group apply physical organic chemistry to the study of environmental processes, with a special emphasis on photochemistry. He received his B.A. in Chemistry from Reed College (Portland, Oregon) in 1992 and his Ph.D. in Chemistry from the University of California, Berkeley in 1997. At Berkeley, he was co-advised by Professors Robert Bergman and Richard Andersen. Following his PhD, he switched his research focus from organometallic chemistry to environmental chemistry. He was a postdoctoral researcher at MIT from 1997 to 1999 with Prof. Philip Gschwend in the department of Civil and Environmental Engineering. McNeill began his independent career as a faculty member at the University of Minnesota in the Department of Chemistry, holding ranks of Assistant Professor (2000-2006) and Associate Professor (2007-2009). In 2009, Kris McNeill joined the faculty of ETH Zurich. Title of lecture: Organic Matter Photochemistry and the Sulfur Cycle PL Martha J.M. Wells Short CV: Martha J.M. Wells Ph.D. is Professor of Chemistry, Emeritus, Tennessee Technological University, USA, and sole proprietor of EnviroChem Services, a small business consulting firm. She received her B.S. degree from Eastern Kentucky University, and M.S. and Ph.D. degrees from Auburn University. From professional research, teaching, and administrative positions in government, industry, and academia, Wells gained wide-ranging experience with legacy and emerging contaminants including herbicides, pharmaceuticals, and PFAS. She conducted extensive research in analytical extractions and chromatographic, spectroscopic, and spectrometric separations for studies in freshwater, drinking water, wastewater, soil, and fishes, and studies fluorescence EEM-PARAFAC monitoring organic matter in water reuse. Relevant to this presentation, she discusses her research on the supramolecular structure and dynamic aggregation of aquatic NOM and EfOM. She is a member of IHSS and IWA. Wells was inducted into the 2017 class of American Chemical Society (ACS) Fellows, and this year celebrates 50 years of ACS membership. Title of lecture: Supramolecular structure of NOM and EfOM: Analytical Evidence PL Speakers
