In the recent years, modeling approaches have become one of the principal means by which the gaps between current basic process knowledge and predictions in environmental sciences can be bridged. The scientific challenges that must be addressed in these modeling approaches include the multi-scale description of highly heterogeneous systems with discontinuities in physical and chemical properties, and coupling of thermal, hydrological, chemical, mechanical and biological processes. Pores are the location where these couplings take place.


The objective of our group “Porous media” is the development of integrated predictive reactive transport modeling approaches that cover a large range of pressure, temperature and salinity conditions, in order to encompass supergene to hydrothermal conditions, in the presence of fresh water as well as brine.  To this end, our team explore mechanistic couplings of basic processes with experimental and numerical modeling approaches.
