Hello! I am working on AI, market design, and the economics of technology, primarily in the context of online platforms, social media, and marketing. I am an assistant professor of Information, Technology, and Operations at the Fordham Gabelli School of Business, and a research affiliate at the MIT Initiative on the Digital Economy (IDE). I earned my Ph.D. degree in Operations Management and Information Systems from NYU Stern School of Business, and my B.Sc. in Computer Science from the University of Patras, Greece.
My recent research has examined the design of reputation, pricing, search, advertising, and matching systems in online marketplaces, the design of social media platforms, and the economic and public policy implications of the sharing economy. My work has appeared in academic and popular press venues such as Management Science, Marketing Science, the ACM conference on Economics and Computation, the Federal Reserve Bank of San Francisco, the Washington Post, the LA Times, the Financial Times, and NPR.
