About me

I'm the Co-Founder & CTO of b12 Labs (YC S25), where we're building the chemistry copilot for pharma and biotech. We turn natural language into automated lab experiments — compressing timelines from months to days.

Before b12, I built the first AI agent capable of autonomously planning and making molecules in a robotic lab, published in Nature Machine Intelligence (750+ citations, best paper at NeurIPS AI for Science). My research at EPFL focused on the development and application of Language Models to tackle common day-to-day problems from chemists — from improving accessibility to computational tools, to fully automating synthesis pipelines, to accelerating the discovery of new molecules and materials.
