Physicist. Agent behavior & evals. Communicating about AI & science.
§01 — ABOUT
During my studies I worked on projects in space technology, fundamental particle physics, antimatter, solar cells and fusion energy — and helped make the most precise measurement of an atomic nucleus's size in the world.
As a fusion researcher, I built and deployed a plasma thermometer (Langmuir probe) to measure interchange instability. In early 2025, I became convinced that AI will have the single greatest impact on the world over the next 5-10 years, including in physics, so I pivoted my focus there.
I started working at a friend's startup building some of the first large-scale agents. There I have optimized LLM costs and invented agent vents.
On the side, I run monthly AI briefings for Swedish MPs with Niels Paarup-Petersen (C), and make the podcast AI med Jonas & Benjamin (in Swedish) with Jonas von Essen.
