Short Bio

Beginning in 2025, I am Professor of Mathematics in the Department of Mathematics Education, Hongik University in Seoul, Korea. During 2007--2024, I have worked in Muhlenberg College in Allentown, Pennsylvania. Before coming to Muhlenberg, I taught at Hendrix College in Conway, Arkansas for three years. During my Ph.D. program at Johns Hopkins University in Baltimore, Maryland, I specialized in number theory. My current research interests include elliptic curves, distribution of zeros of various L-functions, and intrinsic Diophantine approximations. More generally, I am interested in anything related to prime numbers, such as 2, 3, 5, 7, etc.
