I am an associate professor in the Department of Mathematical Sciences at UNIST (Ulsan National Institute for Science and Technology). My research centers around the arithmetic of special values of various L-functions and their p-adic avatars, namely p-adic L-functions:  vanishing of µ-invariants of various cyclotomic p-adic L-functions and (complex and residual) non-vanishing of special L-values with cyclotomic twists. I am also interested in horizontal non-vanishing of the L-values, algebraic-differential independence of p-adic L-functions, and distribution of continued fractions.
