Research Interests

I am a chemical oceanographer and trace metal biogeochemist who studies the interactions between biotic and abiotic marine particles.

Some of the questions my research hopes to answer:

How do lithogenic particles (non-living minerals) and biogenic particles (living and recently living organisms) influence the distributions of each other? What do particle distributions tell us about lithogenic inputs, the past and present state of the biological pump, and dynamics affecting particle type/size/flux?

What are the dominant mechanisms by which organisms access lithogenic and other refractory trace metal pools? What are the rates of these processes, which organisms or communities conduct them, and where are they oceanographically important?

How do marine organisms and ecosystems respond to variations in particulate metal inputs? How can we leverage biogeochemical models to examine the sensitivities of marine biological and chemical systems to various forcings?
