The Integrated Science Library features a digital science center providing research and data support for students and faculty in a high-end, technology-rich facility, with flexible spaces for collaborative work, and core literature along with current reading collections in the sciences.  The new library houses collections for biology, chemistry, physics & astronomy and psychology.

Lecture Hall
A 165 seat lecture hall with auditorium seating is located on the 5th and 6th floors. In addition, a 25 seat classroom is located on the 6th floor, and a small seminar room is located on the 7th floor.

Research Laboratories
The 7th to the 14th floors are designed to foster interdisciplinary interaction and collaboration around common research interests.  For example, the 7th floor is colloquially known as the “Nano floor” as it houses laboratories for Principal Investigators from each of the Departments of Physics, Mechanical Engineering and Electrical Engineering.  Each PI has his or her own lab, but there are common areas where instrumentation is shared.  Meeting spaces are jointly shared and a mezzanine above the PI’s offices provides common seating for graduate students and post-docs.  On other floors there are groups from the Departments of Biological Sciences, Chemistry, Applied Physics & Applied Mathematics, and Biomedical Engineering.  (See  Several of the floors now being completed will house current faculty and recruits to Columbia’s new Institute for Data Sciences and Engineering.
