Postdoctoral Associates

  • Anders Torstensson WELCOME! to Anders who will come to us late summer/early autumn 2016 from the University of Göteborg, Sweden. He will work with Jodi Young and Jody Deming on the response of polar marine ecosystems to salinity changes as a part of the Future of Ice Initiative.

Current Graduate Students

  • Zachary Cooper WELCOME! to Zachary who will join us this summer 2016 from the University of Georgia.  He will begin working on 34H/phage 9A interactions and host specificity in environmental extremes.
  • Gordon “Max” Showalter, studies bacterial swimming behaviors (motility) in cold and subzero temperatures to help understand microbial colonization of sea ice and pursue the use of motility as a biosignature in extreme and extraterrestrial environments. (gshowalt AT uw DOT edu).  Check out his Town Hall talk.  He attended NSF’s 10th Antarctic Biology Training Program at Palmer Station this summer 2016.
  • Evan Firth, got her MS on an NSF-funded project on Seasonal Synergy between Bacterial Osmoprotection and Algal Production in Sea Ice (firth.evan AT Evan attended the 2013 May Sea Ice Field Course.  Evan is currently involved in an AB rotation (2016) in Dr. Catling’s lab measuring the microbial tolerance of Martian brine solutions.

UW Astrobiology Rotation Students/Visiting Students

  • Paul Kintner (UW AB program) examining the fractionation of bacteria in sea ice as it freezes with respect to freezing rate and the presence of gels. (kintner AT uw DOT edu).
