Nayun Kim


Dr. Kim received her B.S. in Chemistry at the University of Chicago. She then did her Ph. D. thesis research with Ursula Storb in the department of Biochemistry and Molecular Biology at the University of Chicago studying the mechanism of somatic hypermutations in the mouse and human immunoglobulin genes. Her first postdoctoral research involved characterization of a novel DNA polymerase carried out in the laboratory of Richard Wood at the University of Pittsburgh. She then joined the lab of Sue Jinks-Robertson at Emory University for her second postdoctoral training and begun research into how transcription directly influences genome instability using the Saccharomyces cerevisiae model system. She moved to Duke University with the rest of the Jinks-Robertson lab and was later promoted to research assistant professor. She joined the MMG department at UT Health Science Center at Houston in 2013 as an assistant professor.
