Scott M. Hofer is Professor of Human Development and Family Sciences and Director of the Psychosocial Core in the Center for Healthy Aging Research at the Oregon State University. He received his PhD in psychology from University of Southern California in 1994, under the supervision of Dr. John Horn, and held postdoctoral positions at the Age and Cognitive Performance Research Center at the University of Manchester and the Center for Developmental and Health Genetics at The Pennsylvania State University, where he was promoted to Associate Professor in 2003. His research examines the role of aging and health on changes in cognitive functioning, in interaction with demographic and psychosocial influences, and on statistical analysis and design issues for understanding developmental and aging processes. He collaborates with national and international researchers on longitudinal studies of development and aging and is associate investigator on research networks in Australia, Sweden, and the United Kingdom. He is currently co-leading the development of an international collaborative research network for the Integrative Analysis of Longitudinal Studies on Aging (IALSA), currently involving over 25 longitudinal studies and funded by the National Institute on Aging (R01AG026453-01).

He serves on editorial boards for Gerontology and Multivariate Behavioral Research, as ad hoc reviewer for over 20 journals, and as member of review panels for NIH and internationally. He has co-organized international conferences on aging, most recently The International Conference on the Future of Cognitive Aging Research with Duane Alwin and held at Penn State in May, 2005. A direct outcome of this conference, The Handbook on Cognitive Aging, is currently under contract with Sage with an expected early 2008 publication date.

Ongoing Research

• Integrative analysis of Longitudinal Studies of Aging
• Alternative time-based approaches for explaining aging and health-related heterogeneity in cognition
• Development and evaluation of measurement designs for identifying individual-level change in cognition
• Population inference and statistical analysis of incomplete longitudinal data due to attrition and mortality
• Structure and measurement of personality, cognitive capabilities, and psychopathology
• Modeling change and predictors of change in psychopathology from childhood to young adulthood
