My CV

Brief Biography

I am a PhD student at Columbia Business School. My research interests lie in understanding important and emerging phenomena in marketing, typically those driven by the digital economy, using both theoretical modeling and data-driven approaches (primarily statistical machine learning). My dissertation research focuses on e-commerce platforms and digital advertising. In addition, I am also interested in topics in agency theory and salesforce compensation. Prior to joining Columbia, I received my M.S. degree in Operations Research from Columbia University, and received my B.S. degree in Electronics Engineering from Tsinghua University. I also previously worked as a data scientist at Helix Partners (a hedge fund) and Hewlett-Packard.
