Hello, I am Jean Nellie Liang. I currently serve as President Joe Biden's Under Secretary of the Treasury for Domestic Finance. I obtained my B.A. in economics from the University of Notre Dame in 1979 and went on to complete both my M.A. (1984) and Ph.D. (1986) in economics at the University of Maryland, College Park. My doctoral thesis focused on an empirical conjectural variation model of oligopoly. Prior to my current position, I have had the opportunity to work in various roles in the private sector and academia, providing me with a diverse skill set and valuable experiences.
