Marine Biogeochemistry

Marine Geobiology

Research topics and interests


- Biogeochemical processes in marine sediments
- Marine geobiology and geomicrobiology
- Early Earth live and astrobiology


- benthic N, Fe, S, and C cycling in oxygen minimum zones
- methane in marine systems (cold seeps, gas hydrates, anaerobic oxidation of
  methane, authigenic carbonates)
- microbe-mineral interactions (e.g. carbonate precipitation and dissolution)
- microbial degradation of petroleum in sediments
- microbial alteration of plastics in sediments
- whale falls in the deep sea (chemosynthesis, sulfate reduction, methanogenesis)
