Abstract
Soil and aquifers are porous and topologically complex environments. The flow field is a heterogeneous mosaic of high and low velocities, rheological properties, and partially miscible or immiscible phases (e.g., air and contaminants). Each of these parameters controls chemical mixing and reactions in these environments of high structural complexity. The biochemical activities of microbes also play a major role, both in controlling the local fluid dynamics (by clogging and re-routing of flow due to biofilm formation) and the cycling of nutrients, trace elements, and contaminants in these environments. Firstly, we will consider the consequences of fluid mixing on the kinetics of fluid-fluid and fluid-solid reactions in porous media, focusing in particular on the impact of an immiscible phase such as air. Secondly, we will focus on the consequences of porous media geometry and boundary conditions on microbial processes such as bioclogging, bacterial chemotaxis or soil respiration.
About Joaquin Jiminez-Martinez
Prof. Dr. Joaquin Jiminez-Martinez is a Research Scientist-Group Leader at Eawag (Swiss Federal Institute of Aquatic Science and Technology) and Lecturer and Research Associate at the Department of Civil and Environmental Engineering-ETH Zurich as part of Prof. Roman Stocker’ Group. He is also Guest Scientist at Los Alamos National Laboratory (US).
His research focuses on the study of transport and (bio-)chemical reaction phenomena in porous and fractured media, particularly in multiphase systems. He tackles these problems mainly by experiments performed over scales ranging from micromodels to field scale, and blending them with theory and modeling. He combines his research activities with teaching classes in the Bachelor (undergraduate) and Master (graduate) programs of Civil and Environmental Engineering and Earth Sciences at ETH.
After graduating (BSc) in Geological Sciences from University of Granada (Spain), and to obtain the Certificate of Advanced Studies in Geotechnical Engineering (MSc) at the Technical University of Catalonia (Barcelona, Spain) in 2007, he obtained a PhD degree in Subsurface Hydrology at the same university in 2010. He strengthened his research formation as Postdoctoral Fellow at the CNRS-University of Rennes 1 in France (2010-2012), being awarded as titular of the International Chair on Environment and Innovation (Foundation Rennes 1) (2012-2014). He completed his formation as Post-doc Research Associate at Los Alamos National Laboratory, US (2014-2016).
