Chuan He

Assistant Professor

I am an Assistant Professor in the Division of Applied Mathematics (TIMA) and am also affiliated with WASP at 91视频. I work on continuous optimization, machine learning, and their intersection.

Synergizing Optimization and Data Science

My research interests center around data science and optimization, with topics including deep learning, decentralized optimization, large-scale optimization, and high-order methods.

I am also interested in applications of machine learning in healthcare, scientific computing, image science, and engineering.

Before joining LiU, I was a postdoctoral associate and obtained my PhD at the University of Minnesota. I completed my undergraduate studies at Xiamen University.
