I recently completed my PhD in Computational Cognitive Science at MIT, supervised by Josh Tenenbaum. I spent the first three years mostly developing Bayesian machine learning methods for explainable AI, then the next three years studying attitude formation, political persuasion, and basically how to elect Democrats.
