Nicole Koropatkin received her PhD in Biochemistry from the University of Wisconsin in 2004. Trained in structural enzymology in the lab of Hazel Holden, her graduate work focused on the enymes involved in O-antigen deoxysugar biosynthesis in Salmonella typhi. After finishing her training, she moved to the lab of Thomas Smith at the Donald Danforth Plant Science Center in St. Louis. She received an NRSA to determine the structural basis for nitrate and bicarbonate discrimination within the ABC transport systems of Synechocystis PCC 6803. After completing this study, she teamed up with Eric Martens from the Jeffrey Gordon lab at Washington University in St. Louis in order to investigate the structures of the novel proteins encoded within Bacteroidetes polysaccharide utilization loci. In 2009 she moved to the University of Michigan Medical School. She is currently an Assistant Professor in the Microbiology and Immunology department. The Koropatkin lab studies the structural biology of glycan capture by a variety of human gut bacteria.
