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. He currently serves on the Council of Representatives, Federation of Associations in Behavioral and Brain Sciences.

Dr. Hofer’s research is on the identification and explanation of individual differences in developmental and aging-related processes and involves analysis of existing longitudinal studies, new data collection using intensive measurement designs, and developments in research methodology focused on improving the measurement and analysis of change. He is Program Director of the NIH-funded Integrative Analysis of Longitudinal Studies on Aging and Dementia (IALSA) research network, comprised of over 100 longitudinal studies, for international comparative research and synthesis of results from many different studies. He has used intensive measurement designs to evaluate the within-person day-to-day dynamics among health behaviors, cognition, and well-being to better enable the assessment and identification of critical changes in functioning. He and his colleagues are working to leverage web-based technologies to bring the assessment of neurocognitive and patient-reported outcomes into the home and clinic to enable earlier and more accurate decisions about changes in health, cognition, and quality of life.
