Scholarly Interests

My research is related to the application, development, and assessment of quantitative methods in the social and behavioral sciences. I am particularly interested in methods for causal inferences and estimation of treatment effects. In the quasi-experimental setting I have worked on propensity score methods for the analysis of non-equivalent control group designs, detection of treatment effect heterogeneity, and developed methods for variable selection. In the experimental setting I am interested in design-replication studies and permutation-based statistical tests. I find computationally intensive methods such as regression trees and resampling and reordering methods to be very useful tools in my work.
