Peter Cohan teaches graduate and undergraduate architecture design studios in the Department of Architecture. He has twice received the Lionel Pries Prize for excellence in teaching. He also leads an architecture practice, Peter Cohan Architect, specializing in single-family residential design. His research interests focus on the nature of materials, their expressive role in construction, and the practical application of tectonic theory to architecture. He has written a number of papers and articles on this subject in addition to exploring these issues in teaching and practice.
Cohan also has an abiding interest in Scandinavian architecture. He is the director of the Scan|Design Visiting Guest Professor Program, which annually brings a distinguished Danish architect to teach in the CBE, and the Scan|Design Architecture Internship Program, which provides internships in Denmark for students enrolled in the Master of Architecture programs.
