Ann Li

Undergraduate Computer Science Student at Columbia University ♔

I am a fourth-year computer science student interested in exploring different applications of software. My experience includes working at the intersection of agentic AI and large-scale distributed infrastructure at Google, optimizing system software at the edge of physical AI at NVIDIA, and learning the applications of software in quantitative finance as a Jane Street AMP Scholar.

Apart from computer science, I am also broadly interested in the studies of art history for both visual and performing arts. In my free time, I am a recreational speedcuber, avid 脑综Short for 脑力综艺.
