I am a psychologist and behavioral scientist who studies the systematic difference between what we think “rational” people ought to do, and what people actually do (decision biases).

I use my research on decision bias to design interventions and policies that harness these biases and nudge people toward more socially optimal behavior in domains such as vaccination, healthy diet, and other preventive health behaviors.

Examples of my work include applying the default effect to promote vaccination, using social norms to promote healthy eating among children, and harnessing price transparency and savings framing to increase the appeal of preventive medical procedures.
