The MIT Sociotechnical Systems Research Center (SSRC) is an interdisciplinary research center that focuses on the study of high-impact, complex, sociotechnical systems that shape our world. SSRC brings together faculty, researchers, students and staff from across MIT to study and seek solutions to complex societal challenges that span healthcare, energy, infrastructure networks, environment and international development. Their mission is to develop collaborative, holistic and systems-based approaches that combine knowledge and expertise from engineering and social sciences.

The MIT Transit Lab leverages the value of large-scale, long-term research collaborations across transit agencies. Starting in 1992 under the leadership of Professor Nigel Wilson, the Lab has collaborated with metropolitan transit agencies and departments of transportation worldwide, developing and implementing technology for transit operations and planning. Past and ongoing research sponsors include the Chicago Transit Authority (CTA), Massachusetts Bay Transportation Authority (MBTA), Transport for London (TfL), and Mass Transit Railway (MTR, Hong Kong). These long-term engagements, in addition to projects with other transit agencies and international research centers, provide graduate students unique opportunities for applied research.
