I am now a 2nd year graduate student in the Biophysics and Stochastics Research Group at the University of Utah, advised by Professor Paul Bressloff. Before coming to the University of Utah, I received my MSc in Computational Science and Engineering from Yonsei University, South Korea, advised by Professor Jeehyun Lee and Hee-Dae Kwon, and my BSc in Mathematics from the same university.

I am primarily interested in mathematically and computationally analyzing biological phenomena with stochastic and deterministic differential equations. Currently, I am focusing on intercellular signaling via cytoneme, a long and thin cellular projection, during morphogenesis of cell development.
