Short Biography
Professor Watanabe is a pharmacist, health economist, and outcomes researcher. He serves as a Member of the National Academies of Sciences, Engineering, and Medicine (NASEM) Forum on Drug, Discovery, Development, and Translation. In this capacity, Professor Watanabe has been involved in methods development for pragmatic clinical trials through the FDA-sponsored Real-World Evidence Series and serves on the steering committee for the Drug Research Development in Older Adults Workshop. Professor Watanabe applies real-world data to develop policy solutions to improve patient care, bolster population-health, and reduce medical costs. He was a contributor to the NASEM report Making Medicines Affordable: a National Imperative. His research on health implications of non-optimized medication regimens has been cited in multiple successful state legislative efforts to bolster patient-centered care and medication management, and he has testified before the California Senate Health Panel regarding value of comprehensive medication management services to bolster the health and wellness of Californians enrolled in Medicaid. He is a consultant to the California Health Benefits Review Program of the California State Legislature and served on the Advisory Group on Pain Assessment and Management in Long-Term Care Settings for the Joint Commissions. He is currently appointed to the NASEM committee on Implications of Discarded Weight-Based Medications mandated funded by the Centers for Medicare and Medicaid Services. Dr. Watanabe was the first recipient of the University of Washington/Allergan Global Health Economics and Outcomes Research Fellowship. He received his BS from the University of Washington, his PharmD from the University of Southern California, and his MS and PhD from the University of Washington Comparative Health Outcomes, Policy, and Economics (CHOICE) Institute. He is past recipient of the University of Washington Distinguished Alumnae in Pharmaceutical Science and Research award. He is a past National Academy of Medicine (NAM) Anniversary Fellow in Pharmacy sponsored by the American Association of Colleges of Pharmacy and the American College of Clinical Pharmacy. He currently serves as a Scholar in the NAM Emerging Leaders in Health and Medicine Program and serves as a Distinguished Fellow of the Get the Medications Right Institute.
