Group News

The McNeill Research Group studies environmental chemistry in aquatic systems, with a focus on elucidating reaction mechanisms.  Currently the group is studying photochemical processes in surface waters, the degradation of pharmaceutical and personal care product contaminants, the fate of amino acid-based molecules in natural systems and degradation of synthetic plastics in soil.  The McNeill Group is part of the Environmental Chemistry Group in the Institute for Biogeochemistry and Pollutant Dynamics in the Department of Environmental Systems Science at ETH Zurich.
