Judson A. Brewer

Judson Alyn Brewer (born 1974 ) is an American neuroscientist, psychiatrist, and New York Times best-selling author. He is the director of research and innovation at Brown University's Mindfulness Center, and a professor of psychiatry and behavioral and social sciences at Brown's schools of public health and medicine. He studies mindfulness and how our brains form negative behavior patterns, and has used his research to create treatment programs for anxiety, addictions, and unhealthy habits. Brewer founded MindSciences, Inc. (now known as DrJud), an app-based therapy program for anxiety, overeating and smoking.

Education Brewer earned his B.A. in chemistry from Princeton University, where he graduated cum laude, and his M.D./Ph.D. from Washington University School of Medicine in St. Louis. His Ph.D. was in immunology, and his dissertation explored the immune system's regulation of stress hormones (The Role of Glucocorticoids in Immune System Development). While at Washington University, he became interested in mindfulness meditation and worked in the laboratory of Louis J. Muglia. Brewer attended high school at Brebeuf Preparatory School in Indianapolis.

After training in mindfulness meditation during his medical and graduate studies, Brewer completed a psychiatry residency at the Yale School of Medicine—where he was chief resident of Yale's neuroscience unit—followed by a fellowship in substance abuse. He is board certified in psychiatry from the American Board of Psychiatry and Neurology.

Career Academia In Brewer's early career, he was an assistant professor of psychiatry at the Yale School of Medicine and the medical director of Yale's Therapeutic Neuroscience Clinic. He then joined the University of Massachusetts Medical School as an associate professor and research director of the Mindfulness Center. For ten years, he was a research affiliate at MIT's Department of Brain and Cognitive Sciences. In 2018, he joined the faculty of Brown University, where he is the director of research and innovation at the Mindfulness Center and a professor of psychiatry and social and behavioral sciences.

Michael Pollan wrote that in 2012, Brewer, "using fMRI to study the brains of experienced meditators, noticed that their default-mode networks had also been quieted relative to those of novice meditators. It appears that, with the ego temporarily out of commission, the boundaries between self and world, subject and object, all dissolve. These are hallmarks of the mystical experience."

By 2013 Brewer's focus was on "neurobiological mechanisms underlying the interface between stress, mindfulness and the addictive process, and in developing effective means for the modulation of these processes to better treat substance use disorders." He was also developing measurements of mindfulness practice, using functional MRI methods with real-time feedback to examine effects of mindfulness-training on brain function and mental health. A study on the "Craving To Quit" app found a mechanistic link between reductions in brain reactivity to smoking cues and reductions in cigarette smoking that were specific only to mindfulness training, compared to the National Cancer Institute's QuitGuide app. A single arm study of Unwinding Anxiety published in 2020 found a 57% reduction in anxiety in anxious physicians. A randomized controlled trial of Unwinding Anxiety published in 2021 found a 67% reduction in anxiety in people with Generalized Anxiety Disorder (vs. 14% with usual clinical care). In 2019, MindSciences launched a portal. In 2019 and 2020, MindSciences won the "Health Value Award in Behavioral Health Management", an award "to recognize outstanding services, products, and programs across 34 categories spanning the healthcare industry". Mindsciences was acquired by Sharecare Inc. (Nasdaq SHCR) in 2020.

In 2023 Brewer co-founded College Journey to help high school students navigate the stress of the college application process.

As of 2024, Brewer's research studies have been cited over 15,000 times.

Clinical Brewer's clinical practice has specialized in habit change ranging from anxiety to unhealthy eating to addiction. He began his career at the Veteran's Administration Hospital in West Haven, CT where he was also an assistant professor in the department of psychiatry at the Yale School of Medicine. In 2018, he joined the faculty at the School of Public Health and the Warren Alpert Medical School at Brown University. In 2023, he co-founded Mindshift Recovery, a non-profit organization based on his research, dedicated to helping individuals with addiction that combines app-based training with peer mentorship.

Key teachings Brewer uses U Pandita's quote to illustrate the difference between dopamine secretions and joy: "In their quest for happiness, people mistake excitement of the mind for real happiness." He advises using curiosity as a hack to move the brain's attention away from anxiety and cravings.

Media appearances In an article titled "Our 8 Favorite Books in 2021 for Healthy Living," Tara Parker-Pope wrote in The New York Times that "Dr. Brewer's innovative approach in his new book is to view anxiety as a habit that can be broken." In 2021, Ezra Klein interviewed Brewer about his "counterintuitive approach to dealing with worry, craving and anxiety" for The Ezra Klein Show.

Markham Heid of Time quoted Brewer's explanation of his research findings in 2014: "Basically, meditation helps your brain get out of its own way... It's mostly about being aware of your thoughts and not running after them in your mind." Brewer also had begun to focus on "how mindfulness practice can affect learning processes leading to positive habit change", translating research findings into clinical use, specifically with clinical trials of smoking cessation using neurofeedback with mindfulness. Sandra Gray of UMass Boston wrote of "the striking impact of mindfulness on people trying to quit smoking", describing his interview with Meghna Chakrabarti on WBUR's Radio Boston. Brewer had said, "It seems that in experienced meditators some of these regions [associated with the brain's default mode network] get pretty quiet when they are meditating. There's an activity change in the brain. There's a lot more work to be done, but it's probably letting go of some of these pathways that are laid down each time someone uses." and visited Brewer "to learn more about the cutting-edge brain imaging research he is conducting to confirm that mindfulness can be an effective treatment for addictions to everything from food to tobacco to opioids—even to electronic devices like cell phones."

In addition, Farrah Jarral of Al Jazeera noted in 2016 that traditional addiction treatments have a relapse rate of 70 percent, and she featured Brewer's research, describing him as "a psychiatrist who is using the power of the mind to overcome addiction". Fran Smith wrote in 2017, "In a head-to-head comparison, Brewer showed that mindfulness training was twice as effective as the gold-standard behavioral antismoking program."

Smith added:

When Amanda Lang of Bloomberg TV Canada asked Brewer why employers are interested in mindfulness, he said if employees can develop the wisdom to understand how they and their co-workers' minds work, it could help all work together in a much more seamless manner. When asked about the possible downsides, he did not offer any negatives associated with such a change, but he did mention the importance of working with a teacher or facilitator. Responding to a question from Kevin Kruse of Forbes about the "reward-based learning" model and the role of dopamine in the brain, Brewer said, "Dopamine, it seems, is there to help us learn things. So for example, when something novel happens, we get a spritz of dopamine in our nucleus accumbens. And when this process starts, we get habituated when we have the same thing happen over and over and over." He then described the practice of mindfulness:

Charlotte Liebman quoted Brewer's explanation of counter-productive self-criticism: "When we get caught up in self-referential thinking — the type that happens with rumination, worry, guilt or self-judgment — it activates self-referential brain networks... When we let go of that mental chatter and go easy on ourselves, these same brain regions quiet down." To achieve self-compassion, Brewer recommended using "any practice that helps us stay in the moment and notice what it feels like to get caught up. See how painful that is compared to being kind to ourselves."

TED Talk The subject of Brewer's 2015 TED Talk was "A simple way to break a bad habit". It was the fourth most popular TED talk of the year and as of 2019 had been viewed more than 19 million times.

Personal life Brewer grew up in Indianapolis, Indiana. As a boy, he delivered papers for the Indianapolis News and later received a college scholarship sponsored by the newspaper. Brewer and his wife Mahri live in Massachusetts, where they enjoy hiking, biking, and meditating.
