Associate Professor

I'm new here! The Spivak lab moved to UGA's Department of Marine Science from Woods Hole Oceanographic Institution in January 2019.

I am looking for a postdoc, graduate student, and undergraduate students to join the lab! If you are a prospective postdoc or grad student contact me directly. If you are an undergraduate researcher, please complete this application and send it to me.

Ph.D.: Marine Science. 2008. College of William & Mary, Williamsburg, VA.

A.B.: Biology, Environmental Science concentration, with honors. Minor in English. Magna Cum Laude. 2001. Bryn Mawr College, Bryn Mawr, PA.

Research Interests:

My research group focuses on coastal ecosystem ecology. I seek to develop an integrated understanding of ecological and biogeochemical processes in order to refine the role of estuaries and wetlands in the global carbon cycle and predict the likelihood of recovery from human disturbances. My group uses innovative geochemical tracer approaches, including stable isotopes and lipid biomarkers, in combination with mesocosm and landscape-scale experiments to quantify carbon pathways, transformations, and fate.
