Bio

Zefeng Bai is a visiting assistant professor of applied mathematics in the Mathematics, Analytics, Science, and Technology (MAST) division. He came to the United States as an international student in 2012. Driven by a strong interest in finance and applied statistics and mathematics, Zefeng joined the business PhD program (with a focus on business analytics) at Bentley University and earned his PhD in 2022.

Before joining Babson College, Zefeng taught business statistics, intermediate applied statistics, and managerial statistics at Bentley University. He enjoys studying and exploring new teaching techniques that could help facilitate student-and-instructor interactions in a diverse learning environment. Zefeng's research interest lies primarily in long-term asset management strategy and causal inferences using microeconometrics techniques. Specifically, motivated by the increasing aging populations worldwide, his dissertation examines using the target volatility investment concept to improve existing pension plans. Zefeng is also broadly interested in using statistical and mathematical models to explain business and social phenomena. His research has found applications in asset management, behavioral finance, religion study, and public health.
