Hey! I am Francisco

I am currently an Alignment Scientist at AE Studio. Previously, I was a Senior Fellow at Pivotal Research, where I worked on mechanistic interpretability of large language models with Stefan Heimersheim.

In a past life, I was Head of Product at Delft Networks, a TU Delft spin-out building full-stack entanglement-based quantum networks. I did my PhD with Stephanie Wehner on the topic of quantum repeaters (you can find my thesis here). Before that, I studied Engineering Physics at the University of Lisbon.

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.
