Research Focus

Legal decision-making, including conflicts between expertise and impartiality; discretion and control; equality and individuation; and science and law. Her research addresses how these conflicts influence jury and judicial decision-making, how they affect judgments about fairness, and how courts use and fail to make use of scientific evidence.
