I'm a Professor in the Department of Psychology at Arizona State University. I received my B.A. in Mathematics and Psychology with a concentration in Education from Gettysburg College in 2000, my M.A. and Ph.D. in Psychology at the University of Virginia in Charlottesville, VA (2001-2006). At the University of Virginia I studied structural equation modeling and longitudinal data analysis (e.g., growth curve analysis, longitudinal mixture modeling, longitudinal measurement, and dynamic models) with Jack McArdle and John Nesselroade. After completing my Ph.D., I worked with Bob Pianta as a research associate in the Center for the Advanced Study of Teaching and Learning at the University of Virginia. In 2007, I became an Assistant Professor in the Department of Psychology at the University of California, Davis and in 2011, I was promoted to Associate Professor at the University of California, Davis.
My research interests include multivariate methods for the analysis of change, multiple group and latent class models for understanding divergent developmental processes, nonlinearity in development, and cognitive/achievement development.I teach undergraduate and graduate quantitative courses at ASU including Longitudinal Growth Modeling, Exploratory Data Analysis, and Structural Equation Modeling. I also teach at workshops sponsored by the American Psychological Association's Advanced Training Institute and the Longitudinal Research Institute.
