Dr. Hoffman is a health services researcher with interests in older adult health and the Medicare program. His research focuses on older adults falls, informal and formal caregiving, and hospital readmissions. His work on falls assesses how different research methodologies impact fall prevalence and Medicare expenditure estimates and how caregiving reduces fall risk among disabled and cognitively impaired older adults. His work has been published in leading journals such as Medical Care, Health Services Research, and The Gerontologist. Dr. Hoffman is also interested in examining peer effects on health outcomes in spousal households, with implications for care management approaches for older adults.

Teaching

Dr. Hoffman teaches a course on health policy and health program planning, implementation, and evaluation, and has guest lectured on health care financing to graduate level students. He has also mentored graduate students in the School of Nursing.
