Licheng Guo

My name is Licheng Guo. I received my Ph.D. degree in 2022, my M.S. degree in 2021, both in Computer Science from UCLA. I received my B.S. degree in Electronic Engineering from Zhejiang University in 2018. 

My research focus on co-optimizing HLS compilers (from C++ to RTL) and physical design tools (from RTL to hardware) to improve the circuit maximal freuquency and reduce the compilation time.

I love travelling and aspire to explore every country of this amazing world. I also love music and currently I am actively practicing flute.
