She is interested in how consumers form judgments and make decisions, from underlying mechanisms to applications. She investigates questions at the intersection of consumer behavior, psychology, and economics, with the aim of improving human welfare. Her central research examines psychological biases that can lead consumers to commit errors in budgeting, spending, and borrowing. She also explores how the same biases extend beyond financial domains to choices in other areas. Sussman’s prior experience includes work at Goldman Sachs in its equity research division. She earned a bachelor’s degree from Brown University in cognitive science and economics, and a joint PhD from the psychology department and the Woodrow Wilson School of Public and International Affairs at Princeton University.
