Institute professor is the highest title that can be awarded to a faculty member at the Massachusetts Institute of Technology (MIT), a research university located in Cambridge, Massachusetts, United States. It is analogous to the titles of distinguished professor, university professor, or regents professor used at other universities in recognition of a professor's extraordinary research achievements and dedication to the school. At MIT, institute professors are granted a unique level of freedom and flexibility to pursue their research and teaching interests without regular departmental or school responsibilities; they report only to the provost. Usually no more than twelve professors hold this distinction at any one time.
