I was born in Goettingen, Germany and studied Architecture at the Technical University in Munich, and at the Architectural Association School of Architecture in London. I received my Ph.D. in the History of Architecture at the Technical University in Munich. I came to Brown University in 1989 as a visiting professor, and became assistant professor in 1991. My research concentrates mostly on late 19th and early 20th Century Architecture. I have published essays on the history of building materials, architectural illumination, individual buildings and projects, and books on German skyscrapers of the 1920s, on the history of film sets and lighting design. I curated a number of exhibitions, such as "Film Architecture," (Providence, Los Angeles, Frankfurt) "Richard Neutra's Windshield House," (Harvard University, RISD, Washington, Pittsburgh) "Unbuilt Providence," (Brown University) "Friedrich St. Florian: Retrospective," (Brown University) "Luminous Buildings: Architecture of the Night" (Stuttgart and Rotterdam) and edited their catalogues.
