Research summary: I develop and apply methods to measure gases and other geochemical 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
