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 Delaware coastal ecosystems to hydrothermal systems and seafloor methane seeps.
2025 Cruise Blogs
We have been busy sailing the oceans blue in 2025, gathering up hydrothermal and methane seep samples that will keep us busy for the next few years. Check out cruise blogs from our expeditions to sample from:
-
- hydrothermal vents at the East Pacific Rise at 9N: https://storymaps.arcgis.com/stories/05ed89873e1244b5bf7b358664bef583.
- and methane bubble plumes on the U.S. Atlantic Margin: https://storymaps.arcgis.com/collections/21851585a3fa47188f36dfafd8cd3f52?item=3I.
Recruiting a new Ph.D. Student
Interested in joining us? We are looking for a Ph.D. student for a project investigating microbial biogeochemistry and organic carbon exchange between cool, aging oceanic crust and the deep ocean. More information can be found in this position description (PDF) or by getting in touch via email with a short statement of interest and your CV.
