Interdisciplinary Biological Sciences Program

Degree Types: PhD

The Interdisciplinary Biological Sciences (IBiS) Program provides the resources and training environment necessary to promote the development of Ph.D. students into independent, creative research scientists and teachers. The program includes approximately 55 training faculty from diverse science and engineering departments on Northwestern's main campus, who are linked by common interests in addressing fundamental questions in the biological and biomedical sciences.

Increasingly, the life sciences require interdisciplinary approaches in order to make essential progress in understanding normal cellular processes, diseases such as cancer, and the development of complex systems. With closely connected faculty from the departments of Molecular Biosciences, Biomedical Engineering, Neurobiology, Chemistry, and Chemical and Biological Engineering, and with strong ties to numerous interdisciplinary centers including the Center for Cell and Developmental Systems Biology, the Chemistry of Life Processes Institute, the Center for Structural Biology, and the NSF-Simons Center for Quantitative Biology, IBiS promotes innovative research that crosses traditional disciplinary boundaries.

IBiS students also benefit from a close-knit scientific community, a supportive advising structure, an active and involved student organization that sponsors scientific and social activities, and a multifaceted professional development program that further prepares them for a broad range of post-degree career options in academia, industry, teaching and other areas.
