Lifespan development

Scott M. Hofer is Director of the Institute on Aging and Lifelong Health, Professor of Psychology, and holds the Harald Mohr, M.D. and Wilhelma Mohr, M.D. Research Chair in Adult Development and Aging at the University of Victoria. He is Past President of Division 5 (Quantitative and Qualitative Methods) of the American Psychological Association, Past President of the Society of Multivariate Experimental Psychology, and a Fellow of the Academy of Behavioral Medicine Research, American Psychological Association, Canadian Academy of Health Sciences, Gerontological Society of America, and the Royal Statistical Society. In 2016, he received an honorary doctorate from the University of Gothenburg.

Dr. Hofer’s research has focused on the replicability and generalizability of results from longitudinal studies in the psychological and health sciences, with particular emphasis on integrative data analysis and innovations in study design and measurement. He is Program Director of the NIH-funded Integrative Analysis of Longitudinal Studies on Aging and Dementia (IALSA) research network, comprised of over 130 longitudinal studies, for international comparative research and synthesis of results. He has used intensive measurement designs to evaluate the within-person day-to-day dynamics among cognitive and physical health to better enable the assessment and identification of critical changes in functioning and to increase the potential for effective intervention. As Scientific Lead of the Neil and Susan Manning Cognitive Health Initiative, he and his colleagues are leveraging digital technologies to improve the assessment of neurocognitive and patient-reported outcomes into the home and clinic to enable earlier and more accurate detection of change and improve the diagnosis and treatment of individuals with dementia.
