Xingjian ZHENG (郑行健)

Welcome to my site! I am a fifth-year PhD candidate in Finance at Shanghai Advanced Institute of Finance (SAIF), SJTU. My research interests focus on behavioral economics/finance, leveraging Fintech platforms and LLMs. My current research questions are: (1) How to persuade investors with information design on fintech platforms? and (2) What are the “cognitive” decision-making rules of LLMs as economic agents?

My committee chair is Prof. Feng LI, and I am expected to graduate in 2026-27. I am currently visiting HBS this academic year, advised by Prof. Lauren Cohen.

My first name can be pronounced as “Sing-Jan”. Hope to see you in person!
