str1: At MIT, pushing the boundaries of knowledge and possibility is our joyful obsession, and we celebrate fundamental discoveries and practical applications alike. As educators, we also value research as a potent form of learning by doing. Through MIT’s Undergraduate Research Opportunities Program (UROP(opens in new window)), more than 85% of undergraduates enrich their education through engaging in frontline, faculty-led research.
