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, enhance access and equity for marginalized populations and reduce medical costs. He was a contributor to the NASEM report Making Medicines Affordable: a National Imperative and served on the committee for the Medications in Single-Dose Vials: Implications of Discarded Drugs
Report. He has provided briefings to the Centers for Medicare and Medicaid Services, United States Senate Finance, Appropriations, House Ways and Means, Senate HELP, and House Energy and Commerce Committee and Briefings to United States House of Representatives Appropriations Committee Staff on the implications of discarded medications and steps to take to reduce wasted medications. 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 has been involved in national quality metrics development on long-term care and transitions of care with prior service on the Pharmacy Quality Alliance. He has previously served on the American Academy of Neurology Neurotherapies Workgroup on Pharmacoeconomics. 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.
