Hello, I’m Grace

AI engineer building agent-powered data analytics.

I’m Grace, recent Berkeley EECS grad hyped about leveraging machine learning to transform the way people work and live.

Previously, I interned at Jane Street and PEAK6 as a quantitative trading intern. Prior to my stint in quant finance, I was a software engineering intern at Roblox and a machine learning researcher at Berkeley AI Research Lab advised by Prof. Sergey Levine (Berkeley) and Prof. Kuan Fang (Cornell).

In my spare time, I enjoy playing poker, solving puzzles, and reading. I'm also usually tinkering on some side project. Would love to hear about anything you're working on!

If you'd like to connect, please feel free to add me on LinkedIn here.
