Philip Brunner, a professor at the Center for Hydrogeology and Geothermics (CHYN), University of Neuchatel, Switzerland, obtained his PhD from ETH Zurich and conducted postdoctoral research at Flinders University, Australia. He leads the “Hydrogeological Processes” group since 2012 and served as CHYN’s Institute Director from 2018 to 2022. His research aims to develop tools for sustainable water resource management, applying interdisciplinary methods including numerical modeling and tracer hydrology. Philip’s work extends beyond hydrogeology, impacting fields like agriculture, ecohydrology, and engineering for sustainable resource use.


Oliver S. Schilling is Assistant Professor of Hydrogeology at the University of Basel and head of the tracer hydrogeology research group at Eawag, the Swiss Federal Institute of Aquatic Science and Technology. He has obtained his PhD from University of Neuchâtel and spent several years doing research at Laval University in Canada, and CSIRO and Flinders University in Australia. His research focuses on better understanding the interactions between surface water bodies, shallow aquifers, and deep groundwater resources, with the aim to develop approaches for more resilient and sustainable drinking water production, geothermal energy exploration, agricultural water use, and ecosystem restoration. He’s been actively developing and combining new and established hydrological tracer techniques for the study of gas, nutrient, and pathogen transport in groundwater, and currently employs these techniques in several research projects focused on sustainable agricultural water retention and crop nutrient management.
