I like to combine molecular and chemical techniques to answer biogeochemical questions. I study the anaerobic N cycle in either the Black Sea or oceanic oxygen minimum zones. In this position, I have combined metagenomics on samples from the Eastern Tropical North Pacific Oxygen Minimum Zone with in situ nitrogen gas measurements. Future work includes examining rates and microbes of the N cycle on sediment trap material in the OMZ.
