Rebekah Herrman, PhD

Post Doctoral Research Associate


Dr. Rebekah Herrman is a postdoctoral researcher in the Industrial and Systems Engineering department at the University of Tennessee Knoxville. She received her Ph.D. in mathematics in 2020 from the University of Memphis with a focus in combinatorics. While there, she studied graph theory games and optimization problems on graphs. Aside from graph theory, her current research interest is quantum optimization, specifically the quantum approximate optimization algorithm.
