Hillary L. Sullivan Ph.D.

I am a biogeochemist studying how human-induced activities and land use affect the structure and function of ecosystems. I received my Ph.D. in Marine Science from Northeastern University, studying the impact of hydrology on biogeochemical cycling in salt marshes. I work in New England salt marshes studying the impact of hydrologic restoration with runnels on carbon and nitrogen cycling. Through a NOAA graduate fellowship, I am helping with restoration efforts at the Waquoit Bay National Estuarine Research Reserve.

I previously contributed to the TIDE project, a long-term ecosystem-wide nutrient enrichment experiment in the salt marshes of Plum Island, Massachusetts. The study aimed to assess how fertilizer and resulting nitrogen loads are affecting salt marsh nutrient retention and cycling, and consequently, marsh structure. I also helped study nutrient uptake in Brazilian riparian streams.

Prior to joining Woodwell Climate, I worked at the Marine Biological Laboratory and the Louisiana Universities Marine Consortium. I received both my B.A. in environmental science with a concentration in conservation and biology and my M.S. in biology from Clark University.
