Research Interests

I am interested in the use and development of reactive transport models to understand the effects of coupled physical and chemical processes in geological systems.
Current research projects include fluid/rock interaction in oceanic hydrothermal systems, geochemical implications of geothermal energy production and diffusion-dominated reactive transport in low-permeability rocks
