Building Self-Evolving Scientific Agents.

I build Self-Evolving Scientific Agents—systems that move beyond probabilistic prediction to rigorous understanding.

My research bridges Neuro-Symbolic Reasoning, Robust Post-Training, and Generative World Modeling powered by Diffusion. By integrating structured chemical knowledge with verifiable reasoning loops, I aim to enable the autonomous discovery of new chemistry.

Research Pillars

Neuro-Symbolic Reasoning

Injecting symbolic rigor into neural generation. I build architectures that use logic verifiers to eliminate hallucinations in high-stakes scientific reasoning.

Diffusion Models

Moving beyond autoregressive limits. I develop Discrete Diffusion models that generate chemically valid structures and reaction pathways with precise controllability.

Agentic RAG

Orchestrating multi-agent workforces that curate and reason over messy scientific literature, building a dynamic World Graph of chemistry.
