Hi, I am Zhaoying Li, a Postdoc Research Fellow in Computer Science at the National University of Singapore, working with Prof Tulika Mitra. I did my Ph.D. at the same group. I received my B.E. degree in Software Engineering at the Shandong University in 2018.

My research interests include spatial accelerator and compiler optimization.
