I am a Member of Technical Staff at xAI, on Grok reasoning and post-training. My contributions so far: Grok 4.
Previously, I was an EECS undergraduate at UC Berkeley, where I was fortunated to be advised by Ion Stoica and built LMArena. During my undergrad, I also spent a year full-time at Nexusflow as part of the LLM post-training team, collaborating with Banghua Zhu and Jiantao Jiao. Additionally, I briefly worked as a student researcher at Google AI Research, on reasoning.
I am interested in fundamental problems in training large models, building more capable and reliable models, and solving superintelligence. Some of the concrete problems I have been thinking about recently:
- How can we transfer intelligence learned in verifiable domains to open-ended questions?
- Design and formulate less hackable and more interpretable reward signals for presentation and style.
- Scaling multi-agents for training smarter models.
