Skip to main content People Meet the Principal Investigator Angelique Whitehurst, Ph.D. Angelique Whitehurst received her B.A. and B.S. in Chemistry and Biochemistry from Virginia Tech in 1997. She earned her Ph.D. in cell and molecular biology in the lab of Melanie Cobb at UT Southwestern. In her postdoctoral work with Michael White, Ph.D., she developed high-throughput RNAi screens to identify chemosensitizer loci in mammalian cells. Dr. Whitehurst began her independent career in 2009 at the
