Research Statement

My primary field of research interest covers the processes that govern fluid/mineral or fluid/rock interactions from low-temperature conditions up to the pressure and temperature conditions throughout the Earth's crust. The investigation of the dynamics and kinetics of these interactions will lead to a better understanding of many geologic (and technical) processes including mineral reactions in sedimentary basins, weathering, the fate of nanoparticles in the environment, atmospheric and global change, environmental pollution, hydrothermal systems, and the containment of radioactive wastes.

My work includes various experimental techniques using Vertical Scanning Interferometry, Electron and Atomic Force Microscopy and modelling techniques like Monte Carlo and ab initio methods. This approach opens up a new field of study on the surface dynamics on minerals, glasses and metals and their role in water/rock interactions. The possibility of direct measurements of dissolution/ precipitation rates at specific locations on the mineral surface provides a better understanding of reactive surface area. The determination of reactive surface area is known to be a central problem in fluid/solid interactions. Quantitative kinetic rate data are urgently needed for modeling water/rock systems that provide a better understanding of the dynamics governing many geologic processes.
