Research Interests

Structural equation modeling, longitudinal modeling, mixed effects (multilevel) modeling, complex sample data estimation, adolescent development, child maltreatment, healthy aging, work and health

Biography

I received my PhD in Sociology from the University of North Carolina (UNC), Chapel Hill in 2008. My primary area of study was quantitative methods and statistics. Prior to the PhD, I earned an MS from the department of Statistics at UNC. As part of my graduate career, I also worked full time for four years as a Research Statistician at the Odum Institute for Research in Social Science (http://www.irss.unc.edu). After the PhD, I was a postdoctoral fellow for two years at the Center for Developmental Science (http://www.cds.unc.edu/) at UNC where I received training in the theories and methods of human development.

My research includes applications in the social, behavioral, and health sciences, especially statistical models applicable to human health and development processes. My primary tools are structural equation modeling (SEM) with latent variables, multilevel (mixed effects) models, longitudinal modeling, and analysis of complex sample data using a design based (marginal, population average) modeling approach. I teach graduate level statistics courses in all of these areas. Measurement of social constructs, missing data, and selection problems are also foci of my work. My work involves analysis of existing large nationally representative data sets as well as data collected using observation and experimental designs. My own areas of substantive interest are in healthy aging and child maltreatment exposure during adolescence.
