Hi, I'm Bhagyesh, a sophomore majoring in maths and cs. Currently, spending this summer as an exchange student at USTC🇨🇳 spending some of my time working on ricci curvature with Prof. Shiping Liu. I do AI safety research. I consider myself an Iterator — running experiments, iterating on ideas, figuring out what works. But I hope to eventually become a Connector — someone who can look at empirical results and know what they mean at a fundamental level.

Cornell University— Undergraduate Researcherwith Prof. Lionel Levine, Jonathn Chang
SPAR— Spring 2026 — character trainingwith Prof. Lionel Levine
Redwood Research— Blue teamingwith Eric Gan
Algoverse— Evaluation awarenesswith Jord Nguyen
MRM Research AI Team— Adversarial robustnesswith A S Aravinthakshan

I have previously worked on adversarial attacks [AAAI'26], and Value Alignment [ICML'26]. Recently, I have been studying formal verification for autoresearch. See my research and what I’m up to now.

Other things I enjoy include competitive programming, reading blogs, and making new friends. Feel free to reach out and say hi at invi.bhagyesh@gmail.com, though I usually respond faster on social apps.
