My research focuses on microbes (Bacteria, Archaea and microbial Eukaryotes), primarily from marine environments, and how they interact with each other and their environment to form communities that sustain critical ecosystem processes.

Marine microbes are intricately linked to global ecosystems. They perform ~50% of global primary production and mediate processes that drive coastal and open-ocean biogeochemical cycles, including the flux of particulate carbon to the deep ocean. These organisms thus control the fundamental energy base upon which all higher trophic levels depend and modulate the biological ocean carbon pump that helps regulate Earth’s climate.
