About

Hi here. I am Zhang Cao (曹张 in Chinese). Now, I am a first-year postgraduate student of the Chinese University of Hong Kong , majored in Computer Science and Engineering . Currently, I am fortunate to be advised by Patrick Lee .

I am widely interested in system. Currently, I'm looking to focus on MLSys, specially systems for LLMs (e.g., LLM inference). Former, my focus is on Cache System. If you would like to chat, feel free to reach out.
