Group leader at EAWAG and ETH Zürich
The interplay of fluid mixing, chemical reactions and microbial processes in soils
Soil is a porous and topologically complex environment, characterized by high spatio-temporal variability and often fragmented aqueous habitats. The flow field in soils is a heterogeneous mosaic of high and low velocities, rheological properties, and partially miscible or immiscible phases (e.g., air and contaminants), each of which controls chemical mixing and reactions. The biochemical activities of microbes play major roles in the control of pore-scale fluid dynamics and the cycling of nutrients, trace elements, and contaminants in soils. In this seminar, we will first consider the consequences of fluid flow and mixing on the kinetics of fluid-fluid reactions in soils. Second, we will focus on the interplay between hydrodynamics and microbial processes, including bacterial chemotaxis and respiration.
Short bio:
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), where he was awarded the International Chair on Environment and Innovation (Foundation Rennes 1) (2012-2014), and as Post-doc Research Associate at Los Alamos National Laboratory, US (2014-2016). In 2016, he joined Eawag and ETH Zurich as leader of the Subsurface Environmental Processes group and as Lecturer of Groundwater.
