Dr. Christoph Wanner

Biographical Summary

Dr. Christoph Wanner holds a BSc. and MSc. in Earth Sciences as well as a Ph.D. in environmental geochemistry from the University of Bern, Switzerland. After obtaining his PhD in 2011 he moved to the Lawrence Berkeley National Laboratory (LBNL), USA for a 3 year postdoctoral fellowship. In September 2014 he returned to the University of Bern because he was offered a position as “Assistent”. His main research interest is to conduct reactive transport modelling (RTM) to assess the environmental impact caused by naturally occurring and anthropogenic processes. In particular, his focus is on including the fractionation of stable isotopes in RTM simulations to improve the use of such measurements as proxies for (bio)geochemical processes. He has been involved in studies related to the remediation of Cr(VI) and U contaminated sites, natural and enhanced geothermal systems, and silicate weathering.

SCCER-SoE Responsibilities

Christoph Wanner is working with groundwater samples from the Gotthard rail base tunnel to investigate water-rock interaction in a similar environment as at potential future EGS sites in Northern Switzerland. Further, he is carrying out reactive transport model simulations for the Grimsel Pass hydrothermal system, which is currently being investigated within the framework of NRP70. He is also involved in collaborations aiming at unraveling the formation of large amounts of calcite scalings in geothermal wells in the Bavarian Molasse Basin in Germany and using soil gas flux measurements (CO2) as an exploration tool for high enthalpy geothermal systems in Mexico.
