Dr. Choi emigrated from South Korea to pursue her doctoral work at Oregon State University under the tutelage of Dr. Nancy Kerkvliet. In that laboratory, she studied the mechanism of dioxin-induced immune dysfunction. These compounds, unwanted byproducts produced during chlorinated phenoxy herbicide production, are potent environmental contaminants. After completion of her Ph.D. in 2000, Dr. Choi joined Dr.Joseph Craft’s laboratory as a postdoctoral fellow. At Yale, she has been supported by a fellowship from the Arthritis Foundation to investigate how potentially self-reactive T-cells maintain self-tolerance. Her recent publications demonstrate a novel mechanism for maintenance of tolerance by normal T cells, even in the setting of environmental stimuli, such as infectious pathogens, that might otherwise activate potentially auto reactive cells. As an Associate Research Scientist, she plans to continue investigating mechanisms of tolerance maintenance, and how these mechanisms go awry in autoimmunity. Dr. Choi lives in North Haven with her husband, a computer engineer, and two children who attend public schools in the area.
