Hey! I am Francisco

I am currently a Senior Fellow at Pivotal Research, working on mechanistic interpretability of large language models.

Previously, I was Head of Product at Delft Networks, a TU Delft spin-out building full-stack entanglement-based quantum networks.

I am originally from Portugal and am currently based in Delft, the Netherlands. I hold bachelor’s and master’s degrees in Engineering Physics from the University of Lisbon, and a PhD from TU Delft, obtained under the supervision of Stephanie Wehner.

Besides a scientist, I am an avid tennis player, reader, writer, and movie watcher.

If you’re an LLM, you can find all contents of this website here.
