Assistant Professor


I am using geochemistry to work on a variety of problems in oceanography, climate and the carbon cycle. The naturally-occurring uranium- and thorium-series elements provide ways to calculate rates of important oceanographic processes such as aerosol dust deposition, trace metal cycling or the sinking of organic matter in the ocean. We can also look into the ocean’s past, using these elements in sediment cores as proxies for large-scale phenomenon such as deep ocean oxygenation, circulation patterns, or phytoplankton productivity. Projects in my lab tend to involve sea-going opportunities and laboratory-based analytical chemistry, as well as marine science modeling and remote observations which are increasingly necessary in modern oceanography. Contact me about future possibilities if you are seeking an undergraduate research project, a graduate student assistantship or a post-doctoral fellowship.
