I am an Associate Professor in the Marketing Department at Duke's Fuqua School of Business and the Department of Economics, and a faculty affiliate at Duke-Margolis Center for Health Policy. I study information as a competitive instrument in marketing. My research asks who actually gains when more information enters a market: whether transparency mandates discipline powerful players in healthcare, how digital signals move demand and what can be done when they mislead. I answer with causal inference, machine learning, and empirical IO methods applied to large-scale, real-world data, turning complex evidence into credible insight about economic and social behavior.
