Research Interests

My research interests are in the development and application of statistical methods for the social, medical, and biological sciences. One major interest is the combination of results across studies to draw general conclusions (meta-analysis). Another major area of research is the design and analysis of social experiments. I work on the development of statistical methods in both of these areas and their application to policy research, particularly education policy. I also work on the role of uncertainty in cognitive science, trying to understand how human cognition is shaped by the fact that it involves processing of information memory and perception that is inherently uncertain. Some of this work on cognition is supported by the National Science Foundation under a grant for the Spatial Intelligence Learning Center (at Northwestern University, the University of Chicago, and Temple University). Finally, I work on the demography of human abilities, including the understanding of differences between social groups and variation of abilities and measured achievement. My work is support by twelve active grants from the National Science Foundation, the US Institute of Education Sciences, the National Institute of General Medical Sciences, and the Spencer Foundation.
