My research has focused primarily on the development of Bayesian methodology for statistical inference in high dimensional spaces. Specific research problems include Bayesian hierarchical modeling, model selection and model averaging, and predictive density estimation in the decision theory framework. I am particularly interested in prior elicitation and the evaluation of prior choice on Bayesian inference results. The applications of my work range from biostatistics to social sciences and finance.
