Miaosen Chai

I'm an incoming PhD student at UChicagoUniversity of Chicago, advised by Prof. Chenhao Tan. I'm interested in the science of foundation model training and building AI Scientist system that trains the next generation of AI by democratizing the scientific discovery process.

Previously, I received my B.S. in Computer Science from USCUSC, where I had a wonderful time as an undergraduate researcher advised by Prof. Robin Jia, Prof. Willie Neiswanger, and Prof. Jesse Thomason.

In industry, I've spent some time as a researcher at ORNLOak Ridge National Lab and AI2AI2, and as an investor at SequoiaSequoia.

Precise Debugging Benchmark

Precise Debugging Benchmark: Is Your Model Debugging or Regenerating?


Miaosen Chai*, Wang Bill Zhu*, Shangshang Wang, Yejia Liu, Song Bian, Honghua Dong, Willie Neiswanger, Robin Jia
arXiv preprint, 2026
arXiv / Code / Website / BibTeX

A plug-and-paly data engine and benchmark for distinguishing whether a model truly debugs an existing program or simply regenerates it, disentangling repair capability from code generation with new edit-level metrics.
PSALM-V

PSALM-V: Automating Symbolic Planning in Interactive Visual Environments with Large Language Models


Wang Bill Zhu, Miaosen Chai, Ishika Singh, Robin Jia, Jesse Thomason
ICRA 2026
arXiv / Website / BibTeX

PSALM-V automates the induction of symbolic planning models directly from interactive visual environments, letting LLM-driven agents plan reliably without hand-crafted symbolic language for robotics.
Scientific Hypothesis Generation with Mamba

Exploring Scientific Hypothesis Generation with Mamba


Miaosen Chai*, Emily Herron*, Erick Cervantes, Tirthankar Ghosal
NLP4Science @ EMNLP 2024
Anthology / Code / BibTeX

An early exploration of state-space models for open-ended scientific hypothesis generation, examining how Mamba compares to transformer baselines on grounded scientific text.
