I do my best work alone, in long uninterrupted stretches, on questions nobody has tidied up yet. I’d rather be wrong in a way I can measure than right in a way I can’t.
Forecasting keeps score of how often I’m wrong, and for now the score says top forecaster. Next stop is formal methods, where checking is the whole job. Early days. I’m enjoying the road.

2026Data Analyst Intern, OCP Group, Casablanca. Went hunting for unpaid debt in the phosphate rock business. Most of it looked like credits nobody had matched.

2020 – 2024Researcher & Artist, Independent, Paris. Wandered through ecology, biophysics, nutrition, agronomy and geography, writing a research proposal in each. Made thirty-odd poems, photographs and drawings along the way.
