Kaiser Permanente is an integrated health care delivery system with a diverse membership in eight regions across the United States. In the Northern California region, Kaiser Permanente includes a health plan with over 4.5 million members, 21 hospitals and 260 ambulatory medical offices, and a multi-specialty physician group with more than 9,500 physicians. The Division of Research, which is part of Kaiser Permanente Northern California, has more than 600 people on staff, including 57 faculty-level investigators with 350 ongoing, funded projects on a wide range of health research topics. In 2020, the Division's research portfolio included over $125 million in grants awarded by the National Institutes of Health, other federal agencies, private foundations, industry, and Kaiser Permanente. Our investigators have made contributions in many research areas, including disease prevention, patient engagement, chronic illness management, clinical trials, the role of genes and the environment in health, health informatics, and delivery science. Founded in 1961, the Division's research program has been built on a base of externally-funded, rigorous epidemiologic and health services investigati...on. The postdoc may also take advantage of other ongoing training programs within Kaiser Permanente such as the Early Stage Investigators and Delivery Science programs, to facilitate career development.
