At UCSD, my interest in geriatric psychiatry was driven, in part, by a realization of the public-health significance of geriatric care in view of the aging of the population. Starting with one fellow, we developed a geriatric psychiatry program at UCSD and VA San Diego Healthcare System. Today it is the Geriatric Psychiatry Division, with clinical, research, and training components. It includes the Senior Behavioral Health Program, led by my colleague Dan Sewell, and provides comprehensive clinical care to older people with neuropsychiatric disorders. I also direct the Sam and Rose Stein Institute for Research on Aging—a multidisciplinary institute at UCSD dedicated to the development and application of the latest advances in biomedical and behavioral science to issues of successful, healthy aging.
