Research interests

Han’s research primarily focuses on financial market imperfections, such as those generated by asymmetric information, imperfect competition, and bounded memory.

He has studied the role of networks in financial markets, focusing for instance on information networks among market investors and trading and credit networks among financial institutions. He is also interested in questions related to ambiguity in markets, financial fragility, liquidity, and price manipulation.
