Dr. Andrew Hill is a cognitive neuroscientist and lecturer at UCLA. He conducts research on attention and cognitive performance, and he is the Lead Neuroscientist for truBrain, a start-up that offers nootropic supplements, in the form of capsules and drinks (nootropics are drugs that may enhance memory and focus, however much of the research elucidating mechanisms of action of these drugs remains to be done). Dr. Hill is also a cofounder of Alternatives Addiction Treatment, a start-up that offers addiction treatment on the basis of biofeedback, discussed in this episode.
