This is Hejia Zhang, a 2nd-year PhD student in CSE at UCSD, California. I’m current doing AI4EDA and MLsys related research advised by Prof. Jishen Zhao.

My current research interests include:

  1. LLM for better Ditigal Verification and Hardware Design;
  2. Improving performance and efficiency of LLM coding agents.

I was a hardware developer at Akuna Capital, developing low-latency trading system based on SystemVerilog & C++. Before that, I got my bachelor’s degree from Department of EE, Tsinghua University.
