Ladan Mehranvar is a Senior Legal Researcher at the Columbia Center on Sustainable Investment (CCSI). Her work centers on analysing the 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 analysing 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, including on the rights and interests of local communities.
