• Mercury Biogeochemistry
• Trace Metal Biogeochemistry
• Chemical Oceanography
• Marine Particle Stoichiometry

I am motivated by a desire to understand how ecosystems respond to human perturbations of elemental cycles, which I explore from the perspective of microorganismal interactions with their chemical environment under three main themes:

1. mercury mobility and bioavailability in aquatic ecosystems focusing on pathways to human exposure
2. integrative ecological responses to altered growth conditions with implications for marine carbon cycling and mercury bioaccumulation
3. environmental remediation, in particular exploring marine carbon capture techniques through incubation experiments.
