I'm an assistant professor at the Department of Applied Artificial Intelligence at Seoul National University of Science and Technology and PI of Mathematical Machine Learning (MML) lab.
I obtained my Ph.D in mathematics from the University of Wisconsin-Madison under the supervision of Hung Vinh Tran (http://math.wisc.edu/~hung) and did my undergraduate at Pohang University of Science and Technology (POSTECH).
My research interest lies in partial differential equations, optimal control, and machine learning.
