On evaluation

I work on AI evaluation for knowledge work, mostly in life sciences and medical devices — also energy, legal, and finance.

I run Raycaster, which builds benchmarks and environments for that work. I also support evalscience.org, a nonprofit focused on the science of agent evaluation.

Friends know me as an existential pragmatic with a daoist metaphysical temperament and a tragic-humanist sense of life.
