Zhiyu joined the Macro Finance Research (MFR) Program as a Predoctoral Research Professional, working with Professor Lars Peter Hansen. Zhiyu holds a Master of Arts in Computational Social Science with a concentration in Economics from the University of Chicago. Zhiyu‘s research interests span macro finance, asset pricing, machine learning and large language models in finance, and the role of model misspecification and uncertainty in economic decision making. Away from research, Zhiyu is an avid strategy and simulation gamer who builds game mods, currently developing a long-running framework that enables large language models to play open-ended simulation games such as RimWorld, a hands-on way of probing how they make decisions over long horizons.
