Patrick Jaillet holds a joint appointment in the Operations Research and Statistics Group at MIT Sloan and in the Department of Electrical Engineering and Computer Science where he is the Dugald C. Jackson Professor. Jaillet is also a member of the Laboratory for Information and Decision Systems at MIT and Codirector of the MIT Operations Research Center as well as the Faculty Director of the MIT-France program. He was Head of Civil and Environmental Engineering at MIT from 2002 to 2009.
From 1991 to 2002 Jaillet was a Professor at the University of Texas in Austin, the last five years as the Chair of the Department of Management Science and Information Systems within the McCombs School of Business. He cofounded and was Director of UT Austin's Center for Computational Finance. Before his appointment in Austin, he was a faculty and a member of the Center for Applied Mathematics at the École Nationale des Ponts et Chaussée in Paris. He received a Diplôme d'Ingénieur from France (1981), and then came to MIT where he received an SM in Transportation (1982) followed by a PhD in Operations Research (1985).
Jaillet's research interests include online optimization and learning, machine learning, and decision making under uncertainty. His research is funded by US federal sources such as NSF, ONR, AFOSR, and internationally by Singapore. His teaching covers subjects such as machine learning; algorithms; mathematical programming; network science and models; and probability. Jaillet’s consulting activities primarily focus on the development of optimization-based analytic solutions in various industries, including defense, financial, electronic marketplace, and information technology.
He was a Fulbright scholar in 1990 and the recipient of many research and teaching awards. Jaillet is a Fellow of the Institute for Operations Research and Management Science Society (INFORMS), a member of the Mathematical Optimization Society (MOS), and a member of the Society for Industrial and Applied Mathematics (SIAM). He is currently an associate editor for the INFORMS Journal on Optimization, Networks, and Naval Research Logistics. Jaillet was an associate editor for Operations Research from 1994 until 2005 and for Transportation Science from 2002 until 2017.
