Changwoo Lee

I am a fifth year Ph. D. student in the department of Electrical and Computer Engineering at the University of Michigan (U of M), advised by Prof. Hun-Seok Kim.

My research is centered around the efficient machine learning and deep learning models. Specifically, I am interested in the DNN Compression, learnable structural sparsity, and robust and efficient multi-modal systems.

Before I join U of M, I received my M.S. and B.S. at Hanyang University, Seoul, Republic of Korea.
