Dr. Willeumier has served as the Director of Clinical Neuroimaging Research for the Amen Clinics from 2009-2016 to help advance the research mission of exploring how brain SPECT imaging can transform clinical practice. Together with Dr. Amen and colleagues, she led a number of high-profile clinical research trials including investigating the long-term effects of repetitive sub-concussive impacts in NFL football players. From her research, she focused on therapeutic approaches to rehabilitate brain function in athletes and is currently investigating biomarkers for treatment of psychiatric disorders using machine learning applications. Dr. Willeumier conducted her graduate research in the laboratory of Neurophysiology at the University of California, Los Angeles and the laboratory of Neurogenetics at Cedars-Sinai Medical Center using live cell imaging to investigate mechanisms of synaptic signaling in Parkinson’s disease.

Dr. Willeumier received MS degrees in physiological science and neurobiology and a PhD degree in neurobiology from the University of California, Los Angeles. She was a post-doctoral fellow in the Department of Neurology at Cedars-Sinai Medical Center where she continued her work in the field of neurodegenerative disease. She was the recipient of the prestigious NIH fellowship from the National Institute of Mental Health to study the molecular mechanisms underlying Parkinson’s disease and has presented her work at national and international scientific meetings including the Society for Neuroscience, Gordon Conference and the World Brain Mapping Conference.

She has spoken before such prominent organizations as Maria Shriver's Move For Minds, The California Women's Conference, the Professional Compounding Centers of America, the Society for Brain Mapping and Therapeutics, the Academy of Regenerative Medicine, the RAAD Fest, the National Institutes of Health, the Society for Neuroscience, the Gordon Research Conference, Stanford, USC, Thomas Jefferson Law School, the Independent Football Veteran's Conference, the Retired NFL Congress and NFL Player's Association meetings.

A nationally-renowned advocate for brain health, Dr. Willeumier has a passion for sharing her extensive research on brain function and longevity. In addition to her RadioMD podcast, Dr. Willeumier is heard on iHeartRadio with her weekly feature Your Brain Health, and is a featured guest on CNN, KING-TV Seattle, KDVR-TV, Denver, WATN-TV Memphis, KATU-TV, Portland, Sports X Radio, Coast to Coast radio, and magazines including Marie Claire and Swaay.
