Research Interests

Hillary Sullivan is a coastal marine scientist focused on salt marsh biogeochemistry. Her current
PhD research at Northeastern University focuses on the impact of hydrologic alterations on
biogeochemical cycling. Particularly, she is focusing on how nitrogen and carbon cycles are
disrupted after marsh disturbance, and whether they are restored after hydrologic adaptation
strategies are implemented. Ultimately, Hillary hopes to provide knowledge that will both
inform policy and raise awareness for protecting and preserving vital coastal marsh systems.
