Operations Research and Statistics Group

The Operations Research and Statistics (OR/Stat) group at the MIT Sloan School of Management is involved in a wide variety of theoretical and applied topics related to optimization, probability, statistics, and machine learning. Operations Research is the discipline of applying advanced analytical methods to help make better decisions. With the combination of probabilistic modeling expertise and strong optimization skills, the operations research and statistics group is at the cutting edge of developing solutions to the most important data-driven problems facing today’s modern enterprises. The group has strong ties to industry, and works with collaborators in the areas of health care, transportation, energy, airlines, finance, and government. The group is also heavily integrated with the broad community of scholars at MIT who work in the areas of operations research, statistics, machine learning, operations management, industrial engineering, and computer and computational science.

The US News and World Report ranking of quantitative analysis programs consistently ranks our program first year after year, and recently our undergraduate program in Management Science ranked second. We maintain a strong overlap with Sloan’s  Operations Management Group in research, teaching, and student supervision. In 2010, MIT Sloan was awarded the top rank in US News and World Reports Best Business Schools Specialty Rankings in Production / Operations.  The OR/Stat faculty have won numerous prestigious awards including the Glover-Klingman Prize, the INFORMS President Award, INFORMS Expository Writing Award, INFORMS Transportation Science & Logistics Society Best Paper Award, Lanchester Prize, INFORMS Koopman Prize, INFORMS Computing Society Prize, IEEE Leonard G. Abraham Prize, Longuet-Higgins Prize in computer vision and pattern recognition, PECASE and CAREER awards.  Four of our faculty are INFORMS Fellows and two are members of the National Academy of Engineering.

For Prospective Graduate Students in Operations Research and Statistics

Almost all faculty in the operations research and statistics group are members of the Operations Research Center (ORC). Students admitted to the ORC graduate program have the opportunity to learn a strong core curriculum of optimization and probability, and may specialize in any field broadly related to operations research and/or statistics. The ORC has both a PhD program and a masters program. Students interested in applying to this program should look at the admission page here, the prospective student page here and at the letters from current students to incoming students here.
