Research Interests

My research interests include numerical optimization and machine learning. Specifically, I analyze the computational complexity of large scale GPU-parallel algorithms and pursue a broad range of applications in engineering and industrial mathematics, including machine learning.

I am interested in working with SNU students on the topics of optimization, machine learning theory, and machine learning applications.
