My research interests include life-span developmental psychology, adulthood and aging, personality, and the application of advanced methods (e.g., structural, latent mean, latent transition and growth curve modeling, and measurement equivalence) to study developmental processes.
I am particularly interested in examining patterns of intraindividual change and interindividual differences regardless of the substantive topic. I completed my graduate training at The Pennsylvania State University, working with K. Warner Schaie on the Seattle Longitudinal Study. I also did post-doctoral studies in the Psychology Department at University of Victoria, working on the Victoria Longitudinal Study. During this time I developed collaborations with the Betula Project of Memory, Health and Aging in Umeå, Sweden and the Kungsholmen Project in Stockholm, Sweden.
Substantive interests: health and illness; cognition, intellectual abilities and memory; personality and well-being; volunteering in late life; and trajectories and changes in gambling behavior across the lifespan.
Research Interests: modeling temperament and character; stability and change in personality over the lifespan; perceptions and beliefs of older volunteers and studies of psychological and physical benefits of volunteering in older adults; stability and transitions in problem gambling behaviors across the lifespan; and most recently, a longitudinal study of risk behaviors and gambling in youth and emerging adulthood and an intervention study of self-excluded gamblers.
