Steven Cao

I love understanding a system deeply: how it all clicks together, where it gives out, and what it takes to trust it anyway. Right now that means reinforcement learning for humanoid recovery, and getting agents to rewrite code safely at scale. I’m an incoming senior studying cs & math at UC Irvine.

I’ve worked with Unnat Jain on humanoid locomotion, Xiaohui Xie on 3D scene reconstruction, and Hung Cao on biosignals. Three published papers so far, on brainwave identification, brain-injury detection, and fetal heart monitoring. I’ve also interned at Meta through the MLH Fellowship and Crusoe, and I’m a SWE intern at Google right now.

You’ll usually find me on a trail, running some unofficial ultramarathon to see a part of the world I haven’t. I'm drawn to problems where the bottleneck isn't motivation or talent, but rather access.✦

Things I've built:

Highlights

2026 — Google: SWE Intern. Oversight and evaluation for an AI agent that rewrites production Java across the Gmail Android codebase: verification built to resist gaming, and a benchmark that measures whether a prompt or model change actually helped.

2026 — Recoverability Audits: A robot that just caught itself can still be one step from falling, with nothing in its behavior to show it. We score that hidden risk by rolling the state forward 50 times in parallel, distill it into a classifier cheap enough to query continuously, and use it to hand control to a safer policy. Monitors like this are normally trained alongside the policy they watch; ours never touches it, so the same audit drops onto any pre-trained controller.

Giving back:

I keep coming back to teaching and service because I remember what it felt like to not know — to be overwhelmed, unsure if I belonged. These roles aren't side projects; they shape how I think about building things that actually help people.
