I am interested in analyzing expert or professional judgment under conditions of complexity and uncertainty. Why are some judges more accurate than others? How can judgments be improved? I use Brunswik's lens model framework and the lens model equation to analyze various components of expert skill. I am particularly interested in practical applications of judgment and decision research to public policy issues and to improving professional judgment.
