About

Adam Elmachtoub is an Assistant Professor of Industrial Engineering and Operations Research at Columbia University, where he is also a member of the Data Science Institute. His research spans two major themes: (i) designing machine learning and personalization methods to make informed decisions in industries such as retail, logistics, and travel (ii) new models and algorithms for revenue and supply chain management in modern e-commerce and service systems. He previously received his B.S. degree from Cornell in 2009 and his Ph.D. from MIT in 2014, both in operations research. In 2014-2015, he spent one year at the IBM T.J. Watson Research Center working in the area of Smarter Commerce. In 2016, he received an IBM Faculty Award and was one of Forbes 30 under 30 in science.
