Research in Tim Conway’s group aims to understand the geochemistry of trace metals in the marine and earth system, and the role they play as micronutrients and/or toxins in marine biogeochemical cycles, with effects on the global carbon cycle. Researchers working with Dr. Conway employ isotopic techniques including measurement of trace metal (Fe, Zn, Ni, Cd, Cu) isotope ratios by multi-collector HR-ICPMS in a range of materials including aerosol dust, rocks, sediments rain, seawater, ice-cores, marine particles and biological materials. We work closely with national and international collaborators as part of the International GEOTRACES program, working on seawater and other samples collected from all over the world.

New acquisition of a Thermo Neptune Plus MC-ICPMS and Element XR high resolution ICPMS at CMS in 2017, together with an ESI-Seafast flow through system for precise measurement of trace metal concentrations in seawater, provides the group with the ideal resources to utilize and develop these isotopic tracers in order to shed new light on the biogeochemical cycling of these metals in the modern ocean. We are also interested in applying these tracers as proxies for oceanic processes in the geological past.

We are always eager for collaboration in a range of marine and geologic fields, and are always looking for keen and motivated graduate students and postdocs. Please contact us for current opportunities.
