Psychiatrist Judson Brewer is a thought leader in the "science of self mastery," having combined nearly 20 years of experience with mindfulness and scientific research therein. An expert in mindfulness training for addictions, Judson has developed novel treatments to help individuals with substance abuse and eating disorders. He has also studied the neural mechanisms of mindfulness using standard and realtime fMRI, and is translating these findings into clinical use.

In 2012, Judson founded Claritas MindSciences to combine mindfulness and neurofeedback techniques for a variety of conditions; the latest apps are Craving to Quit and Eat Right Now. Judson is currently an Associate Professor of Psychiatry and Medicine at University of Massachusetts School of Medicine, where he is Director of Research at the Center for Mindfulness.

In 2017, Brewer published a book, The Craving Mind: From Cigarettes to Smartphones to Love – Why We Get Hooked and How We Can Break Bad Habits, that unpacks the topic of his TED Talk.
