Associate Professor, Management Science

Biography

Tallys Yunes is a tenured associate professor of management science in the School of Business Administration at the University of Miami. He holds a PhD in operations research from Carnegie Mellon University, as well as BS and MS degrees in computer engineering and computer science from the University of Campinas (UNICAMP) in Brazil.

He has over twenty refereed publications in the areas of constraint programming, integer programming, heuristics, and their integration into hybrid algorithms, with a focus on modeling, computation, and application to practical problems, such as scheduling (sports, personnel, machines), product line simplification, transportation, and information layout. His practical experience includes participating in consulting projects with Burger King’s supply chain management and distribution co-op, Deere & Co., Caterpillar Inc., and Major League Baseball.

Yunes is an associate editor for the INFORMS Journal on Computing and International Transactions in Operational Research. He has served on the program committees of the two main conferences on constraint programming and its hybrids, namely CP-AI-OR and CP, and was a member of the INFORMS Public Information Committee from 2011 to 2013. He helped organize the INFORMS Optimization Society conference in 2012 and the Mixed-Integer Programming (MIP) Workshop in 2016. His primary teaching responsibility at the School is the core MBA course on optimization, for which he has been selected by the students to receive the Excellence in Teaching Award eleven times. In 2015, he received the Faculty Research Mentor of the Year Award for his work with undergraduate business students. In 2017, the faculty of the school awarded him an Excellence in Teaching Award in recognition of outstanding teaching contributions that go beyond the classroom.
