I am currently an Earth Observation Scientist with Plymouth Marine Laboratory. I recently completed an NSERC postdoctoral fellowship in the Department of Earth, Ocean and Atmospheric Sciences at the University of British Columbia, working with Drs. Philippe Tortell and Roger Beckie. I earned my PhD in Chemical Oceanography from the MIT-WHOI Joint Program in Oceanography in 2016.
I develop and apply methods to measure gases and other geochemical tracers in natural waters and the atmosphere, with the aim of improving our quantitative understanding of biogeochemical cycles, both regionally and globally. My research experiences include:
the development of a field-deployable gas equilibration mass spectrometer for measurement of noble gases (Ne, Ar, Kr, and Xe) in water
quantifying photosynthesis and respiration using high-precision isotopic measurements of O2, N2, Ar, and N2O
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
