Educated as organic chemist and later trained as geochemist and geomicrobiologist, I investigate microbial activity and their substrate and energy turnover in the deep subsurface. I use radioactively labeled tracer to determine the in-situ rates of metabolic processes and measure concentrations of potential substrates and metabolic intermediates with highly sensitive methods. My work in the RPL team focusses on the in-situ activity of sulfate reducers in serpentinizing systems under a variety of environmental conditions such as varying pH and substrate concentrations.
