Her primary professional interests are in the areas of tax policy, applied microeconomics, behavioral economics, and the financial crisis. She is particularly interested in exploring how companies choose to replace workers with machines, how consumer theory applies in real world situations, such as surge pricing in the ride-sharing economy, and how game theory and behavioral economics may help explain the causes and consequences of the recent financial crisis and the ongoing crisis in Greece.  She is an expert in the corporate income tax system known as Formulary Apportionment and is regularly invited to speak on the topic.
