About

Welcome to my website! I am a postdoctoral researcher at Olin Business School, Washington University in St. Louis. I’m fortunate to be advised by Prof. Guofu Zhou and Prof. Asaf Manela. My research interests include (Generative) AI in finance, textual analysis, and sell-side analysts. I enjoy both consuming and producing LLMs for financial applications.
