Senior Lab Staff

  • steph

    Stephanie Moore, Lab Manager
    Stephanie oversees day-to-day operations by keeping the mass specs running, making sure the lab space remains tidy, and training new members.

  • Clive

    Clive Jones, Research Scientist
    Clive joined the research group in July 2013, bringing extensive experience with secondary ion mass spectrometry. Here, Clive is the research scientist in charge of our new Cameca ins 7f/geo instrument (which arrived Dec 2013). In this role, Clive spearheads our SIMS-based research investigating micro-scale variations in the carbon and sulfur isotopic composition of biological and sedimentary materials. In addition, Clive facilitates the development of new analytical approaches for the instrument.

  • Jen

    Jennifer Houghton, Research Scientist
    Jen joined the research group in October 2011. Her research projects revolve around biogeochemical interactions between microbes and their environment in complex modern systems, including mid-ocean ridge hydrothermal vents and hypersaline photosynthetic microbial mats. Current projects include investigating the kinetics and fractionation of intermediate sulfur redox species mediated by growth of key hydrothermal microbes, using biogeochemical models to visualize C and S cycling within complex microbial networks, and investigating the effect of diel cycling on C, N, S isotopes of biomass in layered photosynthetic microbial mats.

  • Kärt Paiste, Marie Curie Postdoctoral Scholar
    Kärt joined the research group in October 2020. Her research projects revolve around carbon and sulfur cycling associated with the Great Oxidation Event and she is investigating both pyrite and organic sulfur in bulk sediments and at the micro-scale. She works primarily with sediments from Karelia (Russia) and Gabon.

Graduate Students

  • R. Seth Wood, Ph.D. student
    Seth is a 3rd year student interested in developing a deeper and more rigorous understanding of a suite of carbonate-based geochemical proxies. His research to-date has focused on barite and carbonate mineral precipitation in modern methane seep settings on the Norwegian shelf and Barents Sea.
