My research focuses on climate-driven changes in marine primary production, the foundation of marine food webs. These changes have far-reaching consequences for carbon cycles, species diversity, and the ecosystem services that oceans provide.
Specifically, I study phytoplankton and biogenic tracers in moored sediment traps and seafloor sediment to document changes in the production and composition of phytoplankton assemblages that occur on seasonal to millennial timescales.
The insights gained from this research can help communities and policymakers adapt to the cascading effects of altered primary production.
