Biography
Dr. Langa is the Cyrus Sturgis Professor in the Department of Internal Medicine and Institute for Social Research, a Research Scientist in the Veterans Affairs Center for Clinical Management Research, and an Associate Director of the Institute of Gerontology, all at the University of Michigan. He is also Associate Director of the Health and Retirement Study (HRS), and Principal Investigator of the Harmonized Cognitive Assessment Protocol (HCAP) Project, both funded by the National Institute on Aging.
Dr. Langa received an MD and PhD in Public Policy at the University of Chicago as a Fellow in the Pew Program for Medicine, Arts, and the Social Sciences. He is a General Internist with an active clinical practice treating adult patients, an elected member of the American Society for Clinical Investigation (ASCI), and an elected fellow of the American Association for the Advancement of Science (AAAS).
Dr. Langa’s research focuses on the epidemiology and costs of chronic disease in older adults, with an emphasis on Alzheimer’s disease and related dementias. He has published more than 300 peer-reviewed articles on these topics and is currently studying population trends in dementia prevalence, and the relationship of common cardiovascular risk factors, as well as acute illnesses such as sepsis and stroke, to cognitive decline and dementia. In 2007 and 2015, Dr. Langa was a Visiting Professor at the University of Cambridge, and in 2015 he was also a Visiting Professor at the World Health Organization in Geneva, Switzerland, and the University of California-San Francisco, where he continued work on cross-national comparisons of the epidemiology and outcomes of dementia in the United States, England, and other countries around the world.
