Collaborators

An alphabetical list of other scientists with whom I have ongoing research collaborations.

  • Lihini Aluwihare
    Lihini is a chemical oceanographer at Scripps who is collaborating with us on isotopic studies of the sources and fates of marine organic matter.
  • Chris Charles
    Chris is a paleooceanographer at Scripps. We are working with Chris and his PhD student Lydia Roach to develop D/H records of recent climate change from Swamp Lake in the Sierra Nevada Mountains.
  • Frank Corsetti
    A sedimentologist at USC, Frank has worked on the proposed "Snowball Earth" events. We have collaborated on organic geochemical evidence for environmental conditions during these periods.
  • Konrad Hughen
    Konrad is a paleoclimatologist at WHOI. With his PhD student Nick Drenzek, we are been working to construct D/H records of Holocene climate change from Cariaco Basin sediments.
  • Gordon Love
    An organic geochemist at U.C. Riverside, Gordon is collaborating with us on geochemical investigations of the Neoproterozoic Nanhua Basin in South China.
  • Tim Lyons
    Tim is a geochemist at U.C. Riverside who studies (among other things) the Proterozoic sulfur cycle. We are collaborating with he and Gordon Love on geochemical investigations of the Neoproterozoic Nanhua Basin in South China.
  • Gesine Mollenhauer
    Gesine is an organic geochemist at the University of Bremen in Germany. We are collaborating with her and PhD student Eva Niedermeyer to develop D/H records of Holocene climate change in northwestern Africa.
  • Dianne Newman
    Dianne is a molecular biochemist and geobiologist at MIT. We have been collaborating on studies of the distribution and function of 2-methylhopanoids in photosynthetic bacteria.
  • Adina Paytan
    Adina is a paleooceanographer at U.C. Santa Cruz. We are working with Adina and her PhD student Joe Street to develop D/H records of Holocene climate change from Swamp Lake in the Sierra Nevada Mountains.
  • Ann Pearson
    Another former WHOI postdoc, Ann has been developing methods for measuring rRNA on the moving wire. We've recently published a paper documenting the uptake of 13C from petroleum hydrocarbons by soil bacteria, using her RNA-capture methods.
  • Arndt Schimmelmann
    Arndt and I have been collaborating on a variety of projects since the early days of compound-specific D/H measurements. Current efforts include isotopic measurements of marine POM, kerogens, and development of D-enriched standards.
  • Roger Summons
    Roger has been the driving force behind our investigations of hydrogen isotopes in petroleum. More recently, we have been working on 2-methylhopanoids and on compound-specific S isotopes in oils.
  • David Valentine
    David and I collaborated on an NSF project to study D/H fractionation in sulfate-reducing bacteria, as well as the distribution of hydrogen isotopes in marine sediments.
