I’m a geologist with training in geomicrobiology and low temperature geochemistry. My research at SoWa-RI focuses on biogeochemical studies of aqueous redox transition zones and sediment redox element partitioning. I apply a multi-analytical approach the so-called microcosms genomics, bioelectrochemical, geochemical in situ spectrometric and mineralogical analyses.
