My research aims to decipher the functions/modes of life of uncharacterised anaerobic microbes living in the massive/mostly unexplored marine subsurface, i.e. what are their nutrients/energy sources & how do they conserve energy. We apply complementary methods from gene/genome sequencing, stable isotope probing and experimental enrichments. My current projects investigate the ecology/functions of sulfate-reducing microbes in the Arctic, as well as the ecology/functions of subsurface Chloroflexi.
