Zizhao Chen

{Zizhao, Zoe, 陈梓昭, 梓昭} are equally good with me. I am a CS PhD student at Cornell Tech, working with Yoav Artzi on languages (2024-). Previously I studied robotics as an undergraduate in Toronto and worked there too.

Miscellaneous:

• I attended a workshop and after lunch in my seat sat Yann LeCun.
• I was certified for spending too much time on the Internet.
• I programmed likely world’s least cost-efficient photocopier with a robot arm (video).
• I put a battery in reverse and debugged for an hour (video). More stories like this.
