Since his MSc in Aquatic Ecotoxicology at the University of Amsterdam (2001), Steven Droge has been active in various research projects on the environmental impact of chemical substances. His focus is to understand the chemical behaviour of contaminants in a testing system or in the field, in order to better define the biological response to contaminants. His strategy is to improve models on chemical behaviour by generating consistent high quality data on systematic sets of chemicals and step-by-step variation of other parameters. His PhD work at the Institute for Risk Assessment sciences at Utrecht University unravelled the bioavailability of non-ionic and anionic surfactants in marine sediments. On this topic, he won the Dutch best thesis award on Environmental Sciences in 2008. As a Postdoc at the Helmholtz Research Institute in Leipzig he studied the environmental partition behaviour of cationic surfactants and other organic cationic structures such as biocides and drugs. Since 2012, he returned as a Postdoc to Utrecht University to work on the lipophilicity of organic cations, and supervised research on developing passive sampling techniques for cationic drugs, on fish biotransformation of various types of ionic compounds, and on biodegradability of cationic surfactants.

Soren Eustis was born in Minneapolis, MN (USA), but he spent most of his childhood living in a small town on the banks of the Mississippi River. These experiences instilled in him a great appreciation for the Mississippi and the health of the river ecosystem. He received a BA in Chemistry (ACS Certified) from Grinnell College (Grinnell, IA) in 2003. It was during his tenure at Grinnell that the Ideas of Quantum Chemistry (and some incredibly gifted professors) forever changed the way he saw the world. He received his PhD in Physical Chemistry from Johns Hopkins University in 2009 (Advisor: Prof. Kit H. Bowen). His thesis focused on the spectroscopic signatures of solvated molecules in the gas phase. He then began postdoctoral work at the Swiss Federal Institute of Technology – Zürich (Advisor: Prof. Kris McNeill), where his research included the development of a femtosecond transient absorption and fluorescence instrument to detect short-lived excited state pollutants and photosensitizers in aqueous solutions. In 2012, he joined the faculty of Bowdoin College in Maine, where he serves as an Assistant Professor of Chemistry. His current research interests focus on the application of the theoretical and experimental tools of quantum chemistry to address and mitigate the effects of anthropogenic pollutants in natural waters.

David R. Griffith is an Assistant Professor of Analytical and Environmental Chemistry at Willamette University. His research is focused on characterizing the sources, transformations, and bioactivity of steroidal estrogens in natural waters. David holds a PhD in Environmental Chemistry and Chemical Oceanography from the Massachusetts Institute of Technology/Woods Hole Oceanographic Institution Joint Program (2013). He received his master’s degree in Environmental Science from the Yale School of Forestry and Environmental Studies (2007) and a bachelor’s degree in Chemistry from Bowdoin College (2000). Since then, David has also taught high school science, studied marine fisheries management, and conducted research in isotope biogeochemistry and marine carbon dynamics.

Timothy Julian is the group leader of the Pathogens and Human Health research group in the Department of Environmental Microbiology at Eawag (Dübendorf, Switzerland). The group's mission is to increase the understanding of pathogen transmission at the boundary between humans and the environment to help eliminate infectious disease. Primary research interests are in the fields of pathogen fate and transport, human exposure analyses, quantitative microbial risk assessment, and issues in global water and sanitation provision. Ongoing research projects include work on a broad range of enteric pathogens and antimicrobial resistant bacteria. Before coming to Eawag, Tim worked with Prof. Kellogg J. Schwab as a postdoctoral fellow in the Environmental Health Sciences department at Johns Hopkins Bloomberg School of Public Health (Baltimore, Maryland, USA), and Tim was advised by Prof. Alexandria B. Boehm during his PhD in the Civil and Environmental Engineering Department at Stanford University (Stanford, CA, USA). More information about Tim and his research group can be found via Eawag at:
