Microbes as drivers of global element cycles

We explore how microbes drive small to large scale cycling of elements. We work towards understanding how environmental factors regulate these elemental cycles by shaping the microbial communities involved, both at present and in deep time. We further strive to explain the underlying physiological mechanisms and are actively hunting for yet unknown organisms and novel pathways.
