Marine Biogeochemistry @ UD


Home of Sunita Shah Walter's Research Group
Chicken of the Sea

Our research is focused on the intersection between microbes and carbon cycling in the ocean. We use the tools of organic geochemistry and isotope geochemistry, specializing in biomarker analysis and carbon isotopes, and we work in diverse in environments from hydrothermal systems to the Delaware Bay.

See below for more information about current projects.

I am always looking for enthusiastic and motivated Master’s and Ph.D. students!

If you are interested in working in the Walter Lab, contact me by email.

I am currently recruiting a Ph.D. student to work on an NSF-funded project investigating organic carbon bioavailability in hydrothermally-impacted Guaymas Basin sediments. See linked PDF for more information.
