Professor Hollander is interested in the role of planning and public policy in managing land use and environmental changes associated with economic decline and shrinking cities. He also studies the intersection between technology and planning using virtual, Internet-based communities as laboratories. He has worked in the areas of brownfields redevelopment, sustainability indicators, eco-industrial development, smart decline, and military base reuse. Professor Hollander has written extensively on these topics including peer-reviewed scholarly articles and three books. "Polluted, and Dangerous: America's Worst Abandoned Properties and What Can Be Done About Them" was his first book, published in 2009 by the University of Vermont Press (click here to watch Professor Hollander discussing the book on C-SPAN.) In 2010, he wrote "Principles of Brownfield Regeneration: Cleanup, Design, and Reuse of Derelict Land", with Harvard professor Niall Kirkwood and UEP alum Julia Gold (published by Island Press). In the spring of 2011, his third book was released by Routledge "Sunburnt cities: The Great Recession, depopulation and urban planning in the American Sunbelt".
