Solving hard
problems with AI,
physics & chemistry.

I'm Théo Jaffrelot Inizan — founder at Archean, AI chemist & associate researcher at Berkeley Lab. I build AI that understands physics and chemistry, and point it at the hardest problems in matter.

Portrait of Théo Jaffrelot Inizan

I’m the founder of Archean and an Artificial Intelligence Chemist & Associate Researcher at Lawrence Berkeley National Lab. I build AI that understands physics and chemistry — and point it at the hardest problems in matter.

Previously, I was a researcher at UC Berkeley and Berkeley Lab, working with Omar Yaghi, Kristin Persson, Jennifer Chayes and Christian Borgs on generative AI — from diffusion models to LLMs and foundation atomistic models — to discover, design and understand materials science, chemistry and biology.

Before: PhD at Sorbonne University with Jean-Philip Piquemal, Fulbright scholar at UT Austin, M.Sc. at EPFL.

Research

003 / what I work on
— A

Generative AI for reticular chemistry

LLMs and diffusion models that propose, reason about and refine metal–organic frameworks — MOFGen: from prompt to synthesized crystal.

— B

Universal ML potentials

Machine-learned interatomic potentials for high-throughput prediction — phonons, stability, dynamics.

— C

Polarizable MD & HPC

Tinker-HP, adaptive sampling and hybrid neural/physics simulation at supercomputer scale.

In the lab & beyond

Don’t hesitate to reach out.

Always happy to talk AI, chemistry and materials — questions about MOFGen, the papers, or anything in between.
