He is an international expert on housing and urban development policy, having written extensively on the subject, advised the United Nations, the World Bank, and the Inter-American Development Bank (IDB), and implemented projects on the ground. He currently focuses on documenting urban expansion and densification in a global sample of cities, as well as on advising rapidly growing cities on how to prepare adequate room for their inevitable expansion while making adequate room for the densification of their existing footprints as well.

Shlomo Angel studied architecture and town planning at the Israel Institute of Technology, Haifa, Israel and then obtained a degree in architecture and a PhD in urban and regional planning at the University of California, Berkeley, USA.

His research focuses on urban expansion in a global sample of 120 cities between 1990 and 2000 and on a global sub-sample of 30 cities and their expansion between 1800 and 2000. He has advised the United Nations, the World Bank and the Inter-American Development Bank on housing and urban development policy, as well as conducted housing policy research in dozens of countries.

He is the author of Housing Policy Matters: A Global Analysis (Oxford UP, 2000) and published “An Arterial Grid of Dirt Roads” outlining a strategy for cities in developing countries for making minimal preparations for the impending expansion.
