I received my Ph.D. in statistics from the University of Illinois in 1988, and came to Carnegie Mellon University in 1990. In Fall 2012, I was appointed Associate Dean for Academic Affairs in the university’s Dietrich College of Humanities and Social Sciences.
I am a fellow of the Institute of Mathematical Statistics; a past member of the Board of Trustees and past President of the Psychometric Society; and a fellow of the American Educational Research Association. I am currently co-chair of the Design and Analysis Committee for the National Assessment of Educational Progress (NAEP).
My research interests include Markov Chain Monte Carlo and other computing and estimation
methods, errors in variables, factor analysis and structural equation models in econometrics and psychiatric statistics, statistical analysis of large randomized field trials in education, rating
protocols for teacher quality, and educational data mining.
