Stuart Gaffin is a Research Scientist at the Center for Climate Systems Research, Columbia University, joining in 2003. His current research focuses on NYC’s climate, the urban heat island effect and the role of high-albedo surfaces and urban vegetation, including new types of green infrastructure (and very often green roofs), as mitigation and adaptation strategies for climate change impacts. To initially study these topics, Dr. Gaffin installed a network of green and urban rooftop monitoring and atmospheric research stations throughout the New York City area, including sites in the Bronx, Morningside Heights, Queens and Brooklyn. Dr. Gaffin offered the first courses on the urban heat island effect at Columbia as part of the undergraduate capstone workshop in sustainable development. He currently does most of his data collection and monitoring using FLIR infrared thermography cameras and is studying the micro-climate benefits of green infrastructure with these instruments.
