Siebel Center

Dedicated in 2004, the Thomas M. Siebel Center for Computer Science is the home for the Department of Computer Science at the University of Illinois at Urbana-Champaign. It was made possible by a generous gift from Thomas M. Siebel (MS CS ’85), with additional funding from the State of Illinois and the University of Illinois.

The Siebel Center houses more than 225,000 square feet of classrooms, laboratories, and offices. Since it opened its doors, thousands of students have benefited from the educational and research endeavors within its walls.


Architect Peter Bohlin of Bohlin Cywinski Jackson designed the Siebel Center as a vibrant space that encourages collaboration. Open areas, pervaded by natural light, and informal meeting places sprinkled throughout provide ample opportunities for people to encounter each other. Brick, slate, copper, and glass were used to construct a traditional south-facing exterior to harmonize with the surrounding buildings and a modern north face to reflect the cutting edge activities within. Private offices, quiet spaces, research and instructional labs, classrooms, seminar and conference rooms, a 200-seat auditorium, and a coffee shop fill the interior.
