Ian Bader joined Pei Cobb Freed & Partners in 1981 and was a partner from 1999 to 2020. His built works embrace a wide variety of building types and settings, joining an imaginative response to program and site with a passionate commitment to architecture as an art of building, giving meaning and value to the human condition as it gives shape to the physical world.

Early in his tenure at the firm, Ian made substantive design contributions to such nationally recognized institutional projects as the Meyerson Symphony Center in Dallas and the modernization of the Louvre in Paris. He later played a leading role in the design of the UCLA Anderson School of Management in Los Angeles, Moakley U.S. Courthouse in Boston, and the National Constitution Center in Philadelphia.

As design principle, Ian expanded and enriched the typology of a range of building types, including academic buildings, such as Choate Rosemary Hall Science Center in Wallingford, Connecticut, campuses for the China Europe International Business School in Shanghai, and the CHASS Instruction and Research Facility at UC Riverside; courthouses, such as the U.S. Courthouse in Hammond, Indiana, and the Westchester County Courthouse in New York; and healthcare facilities, such as Bellevue Hospital Ambulatory Care Pavilion and Milstein Family Heart Center in New York. He is responsible for a number of corporate headquarters, including the First International Bank of Israel in Tel Aviv, and many projects on historically sensitive sites, such as Tivoli Hjørnet in Copenhagen and mixed-use developments in central Jerusalem.
