Saskia Sassen is professor of sociology at Columbia University, New York, and at the London School of Economics.
She has been a leader in the study of globalization and the ways the movement of capital, people, and information across borders effects the structure of life in the city. Her 1991 book, The Global City, was a watershed work at a critical time in the evolution of transnationalism and is credited with coining the term, global city. She is an authority on immigration and globalization.
Her other books include Losing Control? Sovereignty in the Age of Globalization (Columbia University Press, 1996) and her latest book is Territory, Authority, and Rights: From Medieval to Global Assemblages (Princeton University Press, 2006), based on a five-year project on governance and accountability in a global economy.
