Research and Teaching Interests：
My fields of research are financial markets and corporate finance. I am particularly interested in how private information, which is not disclosed to the public and is possessed by only a limited number of players (e.g., informed traders, fund managers, CEOs, and/or board members), affects the returns on financial assets and the firm’s corporate finance decisions. I have addressed these issues from both theoretical and empirical perspectives. I teach Principles of Macroeconomics, Money and Banking, Financial Management, and Topics in Finance for IBE students.
