Portrait of Théo Jaffrelot Inizan

I’m part of the founding team of Archean, founder & AI scientist, and an associate researcher at Lawrence Berkeley National Lab. I build AI models that understand physics and chemistry at every level, from the atomistic scale to predicting real-world experiments, with one goal: solving the hardest problems, from quantum sensing to destroying forever chemicals to pulling CO₂ from air.

Previously, I was a researcher at UC Berkeley and Berkeley Lab, working with Omar Yaghi (Nobel Prize in Chemistry 2025), Kristin Persson, Jennifer Chayes, Christian Borgs and Joseph Gonzalez on generative AI to discover and understand materials science and chemistry.

Before: PhD at Sorbonne University and UT Austin (Fulbright scholar) with Jean-Philip Piquemal and Pengyu Ren · M.Sc. at EPFL in Materials & Computer Science with Nicola Marzari and Clémence Corminboeuf · Engineering degree in Materials Science, Institut National Polytechnique.

In the lab & beyond

007 / moments

I like challenges at work and beyond. I have finished three marathons and an ultramarathon, and when I'm not running I'm usually scuba diving (40+ dives across five countries) or practicing my Chinese and Indonesian.
