Interviewer here. In this Profile in Computational Imagination I interview Jonah Gabry a statistician and developer on the Stan team at Columbia. One fun twist is that Jonah was a humanities guy; music, history, languages and literature who was gradually drawn to probability, mathematics and Bayesian statistics through intellectual curiosity. That eventually leads him into programming and building tools to make Bayesian analysis more accessible to classically trained statisticians and domain scientists of all kinds.
