Jiaxin Wen

I'm an incoming CS PhD student at [?]. I'm also a part-time research scientist at Anthropic, working with Ethan Perez and Jan Leike.

Before that, I was a visiting scholar at NYU, advised by He He. I finished my undergrad and Master at Tsinghua University, advised by Minlie Huang.

Research Overview

I want to build AI to tackle challenging tasks beyond human reach. Recently, I'm thinking about these questions:

    • Miscellaneous
    I have passions for a wide variety of fields, and I am constantly exploring new areas and possibilities. Some of my major interests include
    • Sports: I enjoy body building CrossFit recently. I'm aiming to run my first (half-)marathon this year, although it's been a month since my last 30KM running practice because it took me a week to recover :(. I'm also the member of Tsinghua hiking club and rugby team.
    • Literature: I have always been a reader in literature. I served as the teaching assistant for the course "Writing and Communication" in 2021. My favorite authors are Hermann Karl Hesse, Albert Camus, and Jerome David Salinger.
