I am an Associate Professor in Measurement, Statistics and Evaluation in the Department of Human Development and Quantitative Methodology at the University of Maryland. I joined the faculty of EDMS in Fall 2011 after being on the faculty in Psychology at the University of Maryland, Baltimore County and in Educational Psychology at the University of Texas, Austin.
My research interests include the analysis of survey data obtained under complex sampling designs and multilevel latent variable models, including tests of mediation within a multilevel framework.
Prior to earning my Ph.D. in Measurement, Statistics and Evaluation from the University of Maryland in 2001, I was an economist at the Bureau of Labor Statistics and, subsequently, conducted educational research at the American Association of State Colleges and Universities and as Associate Director of institutional research at the University of Maryland.
