UPDATE (24-Aug): All positions have been successfully filled! (Link)


We are looking for three PhD students on two different projects.  The first project involves the environmental photochemistry of amino acid-based biomolecules.  The second project is on the environmen...

Chiheng Chu has a new paper on the photooxidation of histidine and histamine in the presence of natural organic matter (Suwanee River NOM).  His research confirms our previous work that singlet oxygen is the most important oxidant of histidine in such systems, but adds...

Lilli Janssen and Emily Marron have a new paper on the environmental photochemistry of benzotriazole (a triazaindene), indole (a monoazaindene) and the two in-between structures, benzimidazole and indazole.   We have previously examined the photochemistry of indole-con...

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.
