Peiser's primary research has focused on developing an understanding of the response of real estate developers to the market place and to the institutional environment in which they operate, particularly in the areas of urban redevelopment, affordable housing, and suburban sprawl. Current research projects focus on non-performing loans, suburban redevelopment, and new towns. A planner and entrepreneur-developer, as well as an expert in real estate finance, he has also demonstrated an interest in spatial and design issues as well as in the economics of land development. He has been active in the Urban Land Institute, where he is now a Trustee, and of which he has authored numerous publications on his policy-oriented research. In addition to teaching basic courses in development finance, he will also be initiating advanced and postprofessional training programs in this area at the GSD. Peiser received a BA from Yale University, an MBA from Harvard Business School, and a PhD from the University of Cambridge.
