My research focuses on applying decision psychology and behavioral economics to inform practical problems in medical decision making. In particular, my work has applied research about judgment and decision making to the design of patient decision support tools. I am particularly interested in how the inclusion of different elements in patient decision aids either support or bias patients’ decision making processes. Previous research has focused on the impact of patient narratives in decision aids, attitudes towards the use of clinical decision support systems in medicine, and the behavioral economics of noncash incentives.
