I am an Assistant Professor at the Kelley School of Business, Indiana University, and a Research Fellow with the Institute for Environmental and Social Sustainability. My research interests lie in the design and operations of online marketplaces. My current work focuses on information design and growth in two-sided marketplaces. I received my Ph.D. in Operations Management from Robert H. Smith School of Business, University of Maryland, co-advised by Wedad J. Elmaghraby and Kostas Bimpikis (Stanford).
