Saskia Sassen (born January 5, 1947) is a Dutch-American sociologist noted for her analyses of globalization and international human migration.
She is a professor of sociology at Columbia University in New York City, and the London School of Economics.
She studied the impacts of globalisation such as economic restructuring, and how the movements of labour and capital influence urban life.
Sassen observed how nation states begin to lose power to control these developments, and she studied increasing general transnationalism, including transnational human migration.
In the early 2000s, Sassen focused on immigration and globalization, with her "denationalization" and "transnationalism" projects (see Bibliography and External Links, below).
