Lise Johnson leads the Columbia Center on Sustainable Investment's work on investment law and policy. Her work at CCSI centers on analyzing the contractual, legislative, and international legal frameworks governing international investment, and shaping the impacts that those investments have on sustainable development objectives.

She focuses in particular on analyzing international investment treaties and the investor-state arbitrations that arise under them, examining the implications those treaties and cases have for host countries' domestic policies and development strategies. In addition, she concentrates on key institutional and procedural aspects of the legal framework, including efforts to increase transparency in and legitimacy of investor-state dispute settlement.

She has a B.A. from Yale University, J.D. from University of Arizona, LL.M. from Columbia Law School, and is admitted to the bar in California.
