New Postdoctoral Fellows and Researchers

Christopher Dishop received his Ph.D. in Organizational Psychology from Michigan State University in December of 2020. He then spent a year at the U.S. Army Research Institute conducting research with the Foundational Science Research Unit located in Fort Belvoir, Virginia. He is now a postdoctoral fellow in Organizational Behavior and Theory at the Tepper School. His work has appeared in the Journal of Business Research, Computational and Mathematical Organization Theory, Organizational Psychology Review, and Psychological Methods. In his free time, he enjoys playing tag with his nephews, euchre with his friends, and piano with his dad.

Yatharth Dubey is a postdoctoral researcher under the supervision of  Gérard Cornuéjols. Starting July 2023, he will be a tenure-track assistant professor at University of Illinois Urbana-Champaign. Broadly, his research is concerned with strengthening our understanding of the algorithms that allow us to make large-scale discrete decisions — in particular, the algorithms underlying state-of-the-art mixed-integer linear programming (MILP) solvers. Dubey studies both theoretical and practical aspects of branch-and-bound and cutting planes to better solve MILP problems occurring in operations research. He received his Ph.D. from the Georgia Institute of Technology, working with Santanu Dey and Marco Molinaro, in 2022.

Chuqing Jin is a postdoctoral fellow at the Tepper School. She recently completed her Ph.D. in Economics at Boston University. Her research falls at the intersection of industrial organization and applied econometrics, with a focus on applications in the finance and technology industries. In particular, she creates novel models to help understand how information frictions are generated in these industries, as well as how they affect competition and welfare. Combining these models with data, she produces empirical findings to guide policy. Jin’s job market paper uses financial analysts’ forecast data to disentangle their incentives for information provision and derive policy implications for improving information quality in the financial market. When she is not doing economics, she enjoys doing yoga, rock climbing, reading, and going to concerts.
