Postdoctoral Fellow in Astrobiology, McMaster University (November 2009-Present)

  • Early Earth Genomics: I study the evolution of microbes by comparative genomics and mathematical modeling. One such project involves modeling the duplication, deletion, and invention of gene families in Bacteria and Archaea, with the end goal being better constraints on the rates of gene invention versus horizontal gene transfer. Another project uses an infinitely-many-genes model of neutral evolution to predict the sizes of the core and pan-genomes of bacteria. Additional field- and wet-lab-based projects include isolating toluene-degrading halophilic bacteria from saline lakes to investigate the distribution of plasmids associated with BTEX degradation and using bioinformatics to detect genes specifically associated with sulfur isotope fractionation by sulfate reducing bacteria. PIs: Dr. Paul Higgs (McMaster), Dr. Greg Slater (McMaster), Dr. Boswell Wing (McGill)

Ph.D. Biological Oceanography, University of Washington (September 2009)

  • Microbial Evolution In Sea Ice–Communities To Genes: I investigated the diversity of Bacterial and Archaeal communities in winter sea ice utilizing web-enabled software I wrote for the project. I found Archaea and Bacteria from seawater persisted through the winter season with no change in richness and limited changes in the structure of either community. During the Circumpolar Flaw Lead Systems Study I measured the abundances of viruses, bacteria, and dissolved DNA in newly formed sea ice to explore the potential for horizontal gene transfer there. Genomics analyses of the psychrophilic bacterium Colwellia psychrerythraea strain 34H revealed evidence of horizontal gene transfer of a genomic island involved in compatible solute degradation. Advisor: Dr. Jody W. Deming

Certificate in Astrobiology, University of Washington (2009)

  • In vitro microsensor measurements of AOM: I used microsensors to measure the rate of anaerobic oxidation of methane (AOM) in microbial mats from the Black Sea. Advisors: Dr. Dirk de Beer (MPI-Bremen), Dr. Antje Boetius (MPI-Bremen)

M.S. Biological Oceanography, University of Washington (2006)

  • Microbial persistence over an Arctic winter season: I investigated the abundances of bacteria, particles, and particulate extracellular polymeric substances (pEPS) in Arctic winter sea ice during the Canadian Arctic Shelf Exchange study. I observed a significant decline in microbial abundance in the coldest ice, a significant production of pEPS was also detected in all of the ice measured, implying microbial activity in winter sea ice. Advisor: Dr. Jody W. Deming

B.S. Biochemistry with Honors, Washington State University (2002)

  • I consider science outreach an important part of my scientific development and have volunteered my time to a variety of outreach activities, including dozens of hours giving demonstrations at Polar Science Weekend at the Seattle Science Center, the annual School of Oceanography Open House, inside K-6 classrooms, and at sea with the Ocean Inquiry Project. I am currently co-mentoring two `at-risk’ high school students conducting a science fair project on isolating halophilic BTEX-degrading bacteria. In partnership with the Centers for Ocean Sciences Educational Excellence-Ocean Learning Communities (COSEE-OLC), a fellow student and I designed and implemented an ocean sciences curriculum with a local grade school teacher, and I participated in workshops to improve my ability to communicate with citizen scientists, a goal shared by another project I developed to allow engaged amateurs to report and track crows banded by Dr. John Marzluff in the College of Forest Resources at the University of Washington. I have also written articles and shared photographs for publication in non-technical science forums, one of which was subsequently translated and published in Catalan.
