Teaching and Research Fields
I engage in research on asset pricing theory and the construction of its associated models. My work primarily focuses on the stock market, where I analyze diverse datasets to investigate the determinants of stock returns. While traditional finance research has developed theoretical frameworks under the assumption of fully rational investor behavior, actual investment decisions are often deeply human and emotionally driven. Consequently, I am particularly interested in examining how human psychology and behavioral biases influence these established models
