Katie Klier is a second-year Ph.D. candidate at the University of Wisconsin – Madison, in the laboratory of Dr. Karthik Anantharaman. Her research focuses on utilizing metagenomics and other computational techniques to study microbial and viral communities at hydrothermal vents to better understand their contributions to ecology and biogeochemistry. On this cruise, Katie will be collecting deep-sea microbes and viruses using filtration methods. These samples will be brought back to the University of Wisconsin, where they will undergo genomic analysis following nucleic acid extraction and sequencing. Before beginning her position in the Anantharaman lab, Katie earned her B.S. in Cell and Molecular Biology from the University of Michigan and worked for two years as a research fellow at the National Institutes of Health.
