As an undergraduate in biochemistry at Columbia University, Ahn also studied philosophy at Cambridge University’s Pembroke College. Both philosophy and biochemistry led him to Harvard University where he received an M.D. and Ph.D. in neurobiology. “From a neurobiologist’s point of view, how the brain doesn’t work is really about how it does work,” he says.
