Detailed Biography:

Dr. Brennan Spiegel is the Director of Health Services Research for Cedars-Sinai Health System and Professor of Medicine and Public Health at UCLA, where he teaches digital health science, health analytics and health economics.

Dr. Spiegel directs the Cedars-Sinai Center for Outcomes Research and Education (CS-CORE ), a multidisciplinary team that investigates how digital health technologies, including wearable biosensors, smartphone applications, virtual reality, and social media, can strengthen the patient-doctor bond, improve outcomes, and save money. CS-CORE unites clinicians, computer scientists, engineers, statisticians and health services researchers to invent, test, and implement digital innovations for the clinical trenches, always focusing on the value of technology to patient and their providers. His team developed the largest and most widely-documented medical virtual reality program in the world at Cedars-Sinai. He founded Virtual Medicine,  the first international symposium dedicated to medical virtual reality (www.virtualmedicine.health ), and is currently writing Virtual Healing,  a book about therapeutic VR that will publish in 2020 through Basic Books, a leading science publisher. 

Dr. Spiegel has published numerous best-selling medical textbooks, editorials, and more than 200 articles in peer-reviewed journals. He is listed in the Onalytica "Top 100 Influencer" lists for health technology, and is currently the highest ranked academic on this list at #13 in the world. His digital health research has been featured by major media outlets including Bloomberg, the Boston Herald, Forbes, CBS Evening News, Huffington Post, Los Angeles Times, Mashable, NBC News, NPR, PBS, Reuters, The Wall Street Journal, and the Washington Post, among many others. His virtual reality research won the 2017 People’s Voice Webby Award for best technology on the internet. See www.virtualmedicine.health/press  for full media coverage.

Beyond his focus on digital health innovations, Dr. Spiegel conducts research across a wide range of healthcare topics. As a member of the U.S. Food and Drug Administration (FDA) Field Advisory Committee, Dr. Spiegel advises on how to conduct high quality clinical trials. His research is funded by the National Institutes of Health, Patient Centered Outcomes Research Institute (PCORI), Robert Wood Johnson Foundation, Hearst Foundation, Veterans Administration and the California Initiative for the Advancement of Precision Medicine. Dr. Spiegel is Editor-in-Chief of the American Journal of Gastroenterology  – a leading peer-reviewed medical journal. A prolific speaker, Dr. Spiegel is frequently invited to present on his areas of expertise at national and international events, most recently as a keynote speaker at the Consumer Electronics Show, Connected Health Conference, Health 2.0, Health Informatics Medical Society, Exponential Medicine, and the American Psychiatric Association. He practices clinical medicine and maintains an academic teaching practice at Cedars-Sinai Medical Center in Los Angeles, California.
