Hi! I am Jiajun Meng (孟嘉俊), a third-year Ph.D. student at the School of Economics and Management, Beihang University. I received my B.S. in Information Management and Information Systems from Beihang University in 2024.

My research focuses on the area of quantitative marketing and marketing–operations interface, with emphases on online platforms and AI-driven business applications. I also study topics in microeconomics and industrial organization, including consumer search and behavioral economics. I use analytical and game-theoretic modeling in my research.
