Fields of interest:

Marine geochemistry, Paleoclimatology, Paleoceanography, Tracer oceanography, dust, paleoclimate

My research interests involve the application of trace elements and isotopes, such as noble gases, radiogenic, cosmogenic, and extraterrestrial nuclides as well as oxygen, carbon and hydrogen isotopes, to problems at the interface between climate, biogeochemistry, and environmental studies., Most of my studies focus on marine systems, both modern and paleo. More recently, I have started working with ice cores as an archive of past climate conditions.
