Her research relies heavily on “big data” to document various ways in which individuals systematically deviate from making optimal choices. Her work has paid particular attention to the question of what factors produce self-control failures (e.g., under-saving for retirement, exercising too little, eating too much junk food) and how to reduce the incidence of such failures.

She has also explored race and gender discrimination, focusing on how a decision’s context can alter the manifestation of bias. And, she has examined what types of stories are published in The New Yorker as well as what New York Timesstories and science stories are most widely shared (to see a presentation about what types of science stories spread, click here).
