I am currently a second year graduate student in the Geosciences Department at Princeton University studying biological oceanography and biogeochemical cycling with Bess Ward and Jorge Sarmiento. I received a Bachelor of Science in Earth & Environmental Engineering from Columbia University in 2008 and am currently a National Defense Science and Engineering Graduate Fellow.

My research looks at nitrogen loss processes in regions of the oceans depleted of oxygen known as oxygen minimum zones (OMZs). In these regions two competing bacterial processes occur: denitrification (a series of reductions from nitrate to nitrogen gas) an anaerobic ammonium oxidation (a process by which nitrite is combined with ammonium to directly form nitrogen gas). Observations have shown that in the Arabian Sea OMZ, denitrification is by far favored, while in the Peruvian OMZ, anammox is dominant. My aim is to determine why one of these reactions would be favored over another in each of these places, and the results could have profound implications on the carbon cycle and climate change.
