Ocean pollution and acidification
Marine microbiology and microbial ecology
Global biogeochemical cycles

There are half a billion microorganisms in a glass of seawater, and, for the most part, we have no idea what most of these organisms ‘do’ — what they eat, how they survive or how they interact. We do know that the collective activities of these tiny cells drive global cycles of biologically essential elements such as nitrogen and carbon, and we know that global biogeochemical cycles have, in turn, been heavily altered by human activities. The overarching goal of my research is to develop an integrative and predictive understanding of interactions and interplay between microbial ecology, biogeochemical cycling and global change.

For example, his interests include:

  • How different microbial groups and biogeochemical processes interact in expanding oceanic oxygen minimum zones.
  • How nitrogen pollution affects nitrogen cycling and microbial community structure in coastal ecosystems.
  • How coral-associated microbial communities function and how this can be disrupted.
  • How elevated carbon dioxide concentrations influence microbial ecology and biogeochemical cycling in the sea.
