On June 29, 2021, Jeong Ok Choi (최정옥) from GIST and IBS Discrete Mathematics Group gave a talk at the Discrete Math Seminar on the non-singularity of some circulant matrices. The title of her talk was “Invertibility of circulant matrices of arbitrary size“.
On October 27, 2020, Jeong Ok Choi (최정옥) from IBS Discrete Mathematics Group / GIST gave a talk on some game-theoretic problems on graphs, more specifically on the contagion game and the network creation game. The title of her talk was “Various game-theoretic models on graphs“.
The IBS Discrete Mathematics Group welcomes Prof. Jeong Ok Choi (최정옥) from GIST, Gwangju, Korea. She will visit the IBS Discrete Mathematics Group for 1 year until August 31, 2021 during her sabbatical leave from GIST. She received her Ph.D. from University of Illinois at Urbana-Champaign under the supervision of Prof. Douglas West. She was a visiting assistant professor at Furman University and Trinity College. In 2011, she moved to GIST (Gwangju Institute of Science and Technology) in Gwangju, Korea as an assistant professor and she is currently an associate professor.
