Connected to Youngchild Hall by a glass-enclosed atrium, Thomas A. Steitz Hall of Science provides space for the molecular sciences. The building has state-of-the-art research and teaching laboratories, a number of which are shared spaces used by several of the sciences. The chemistry department occupies the first and second floors of the building, and offices and classrooms for biology are found on the top floor. A third-floor bridge within the atrium allows close contact between the biology laboratories and offices in Thomas A. Steitz Hall of Science and those in Youngchild Hall.
