Biography

Mohit Tawarmalani is a Acting Executive Associate Dean of Faculty and Allison and Nancy Schleicher Professor at the Mitchell E. Daniels, Jr. School of Business, Purdue University. He serves as the Academic Director of Krenicki Center for Business Analytics and Machine Learning. He received his Ph.D. and Masters from the University of Illinois at Urbana-Champaign. Prior to that, he received his Bachelors from Indian Institute of Technology, Delhi.

Mohit has worked in the MIS area of Tata Engineering and Locomotive Company (1993-1994) and as a software engineer in geometric modeling at ComputerVision (1995). He teaches courses in business analytics and optimization.

Mohit Tawarmalani’s research interests are at the interface of computer science, optimization, and operations research with applications in business and engineering. Mohit has co-authored a book on global optimization algorithms and has co-authored BARON, a software package widely used for global optimization. Mohit has interest in applications of optimization in harnessing solar energy, building better distillation trains, network systems design, and in understanding economics of business decisions. For his research, Mohit has been awarded the INFORMS Computing Society Prize in 2004, the Best Paper Award from the Workshop on Information Technology and Systems in 2005, and the Beale-Orchard-Hays Prize from the Mathematical Programming Society in 2006. He is also the 2003 Jay N. Ross Young Faculty Scholar and the 2006 Krannert Faculty Fellow.

Mohit was a founding co-director of Purdue’s Masters in Business Analytics and Information Management program, the co-chair of the design committee for Bachelors in Business Analytics and Information Management program, and led the team that won the INFORMS UPS George D. Smith Prize for innovative educational practices in training students to be practitioners of operations research and analytics. He is the recipient of the student-elected Salgo-Noren Foundation Excellence in Teaching award in 2022 and 2023.

Mohit serves as an Associate Editor for the Journal of Global Optimization and for Mathematical Programming Computation. He is a participant of the 2024-2025 Big Ten Academic Alliance Academic Leadership Program. He currently resides in West Lafayette with his wife and their daughter.
