I’m currently working on scaling autonomous science at Intology.

I graduated from the University of Illinois at Urbana-Champaign. My prior research has focused on developing adversarially robust safeguards and alignment techniques for LLMs. My work has been accepted at ICLR, CVPR, NeurIPS, and ICML; also featured in Wired.

Previously, I was a founding engineer at Mindy Group, a Sequoia-backed AI startup. I also co-led Lapis Labs, a student-led research group, and worked at NASA.

    Scaling Automated Post-Training

    Intology

    Locus, our autonomous AI research system, plans and runs experiments over multiple days to improve language models after their initial training. On PostTrainBench+, a benchmark for this post-training process, it achieves 51.6%, exceeding the official human-tuned Qwen3-1.7B-Instruct model (49.4%). Also, an LLM fully post-trained by Locus is currently running in enterprise production.

    NanoGPT-Bench: Can Coding Agents Do Research?

    Intology

    NanoGPT-Bench tests whether AI coding agents can discover ways to train GPT-2 faster, using a fixed computing budget. Given 512 hours of H100 GPU compute, existing SWE coding agents reproduce just 9.3% of the training-speed improvement achieved by human researchers over five months.

    Previewing Locus

    Intology

    We introduce Locus, our autonomous AI research system, which plans, runs, and learns from experiments over multiple days. In a continuous 64-hour run on RE-Bench, a suite of AI research tasks, it scores 1.30 against the human-expert baseline of 1.27. It also earns medals in 77% of the machine-learning competitions in MLE-Bench Lite.
