NeutronGym: Physics-Graded Neutron Instrument Design for LLM Agents
Lijie Ding, Changwoo Do
Designing a scientific instrument tests whether language-model agents can do physics rather than recall it, provided the grading cannot be argued with. We introduce NeutronGym, to…

ColPackAgent: Agent-Skill-Guided Hard-Particle Monte Carlo Workflows for Colloidal Packing
Lijie Ding, Changwoo Do
We introduce ColPackAgent, an agent framework that autonomously runs Monte Carlo simulations of colloidal packing through a Model Context Protocol (MCP) tool server and an agent sk…

Deep Learning the Small-Angle Scattering of Polydisperse Hard Rods
Lijie Ding, Changwoo Do
We present a deep learning framework for modeling and analyzing the small-angle scattering data of polydisperse hard-rod systems, a widely used models for anisotropic colloidal par…
