Curriculum Vitae
I am a Member of Technical Staff at Anthropic, working on Claude post-training.
Previously, I was a Distinguished Research Scientist at Meta AI and technical co-lead for Llama 3. I gave a keynote at CVPR 2025 on the work of the Llama team. Before working on Llama, I led a team of 130+ Meta AI researchers who developed technology to solve grand challenges in the natural sciences. My team delivered research breakthroughs including Cicero, ESM-2 and ESMFold, Llama, and OC22.
Before joining Meta, I worked as an Assistant Professor (with tenure) at Delft University of Technology, and as a post-doctoral researcher under supervision of Lawrence Saul at University of California, San Diego. I received my Ph.D. from Tilburg University in 2009 under the supervision of Eric Postma and Jaap van den Herik. I have visited the labs of Geoffrey Hinton at University of Toronto, and of Maja Pantic at Imperial College London. I obtained an M.Sc. degree in computer science from Maastricht University in 2005.
