Biography

I came to Purdue in the fall of 2010. I received my PhD in Sociology from the University of North Carolina, 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/odum/jsp/home.jsp). 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 primary research is in quantitative methodologies in the social and behavioral sciences. My main focus areas are structural equation modeling (SEM) with latent variables, multilevel (hierarchical, random effects, mixed effects) models, longitudinal modeling, and analysis of complex sample data. Missing data and selection problems are specific topics that I deal with in my research as well. My most recent work has dealt with the application of sampling corrections, for example, sample weights, in mixed effects and longitudinal models and reliability estimation using longitudinal SEMs. A new area of modeling that I am beginning to use in applied work is what I call generalized linear structural equation modeling. This is essentially the combination of generalized linear modeling, which is a framework for modeling outcomes with all types of distributions, and classical structural equation modeling, which formerly only handled quasi-continuous or categorical outcomes.

Broadly my substantive interest is in adolescent development. I am particularly interested in adolescent work life and how that affects development as well as (health, economic, and social) trajectories in adulthood and throughout the life course. I am currently involved in research on adolescent maltreatment (abuse and neglect) and how that affects developmental trajectories in several internalizing and externalizing domains. Most of my work involves analysis of existing, large, nationally representative data sets.
