I’m an Earth Observation Scientist with Plymouth Marine Laboratory. I completed an NSERC postdoctoral fellowship at the University of British Columbia and I earned my PhD in Chemical Oceanography from the MIT-WHOI Joint Program in Oceanography. My research is focused on applying biogeochemical tracers to study carbon, oxygen, and nitrogen cycles in oceanographic and land-based systems.

Research summary:

I develop and apply methods to measure gases and other biogeochemical tracers in the environment, with the aim of improving our quantitative understanding of biogeochemical cycles, both regionally and globally. My research experiences include:
A) the development of a field-deployable gas equilibration mass spectrometer for measurement of noble gases (Ne, Ar, Kr, and Xe) in water
B) quantifying photosynthesis and respiration using high-precision isotopic measurements of O2, N2, Ar, and N2O
C) quantifying air-sea gas exchange in the coastal ocean, ice-covered waters, and groundwater, using measurements of noble gases at natural abundances, and through deliberate tracer releases
D) applying autonomous ocean technology (e.g., biogeochemical Argo floats and surface vehicles) to study ocean carbon and oxygen cycles
