Andrew, who usually goes by “Critch”, earned his PhD in mathematics at UC Berkeley, researching algebro-geometric properties of machine learning models. He completed his B.Sc. with Honors in pure mathematics in just 20 months, and earned the Governor General’s Medal as the top undergraduate student at the Memorial University of Newfoundland that year. At the age of 19 he began his PhD in analytic geometry at the University of Toronto, and switched to studying algebraic geometry at Berkeley in 2008. While at Berkeley, he helped develop much of CFAR’s seed curriculum, drawing from his academic interests in mathematics and cognitive science, and years of tinkering with what we would now call “rationality training.”
