My lab studies how ocean acidification and other changes to seawater chemistry impact calcifying organisms and biogeochemical cycles. The lab is focused on chemical-scale mechanisms in oceanography and climate. We then apply this small-scale understanding to explain global patterns. For example, we study skeletal growth to explain why marine calcifiers exhibit divergent sensitivities to ocean acidification. Other projects use this mechanistic understanding of biomineralization to improve paleoproxies.
