Edward Rothberg
Chairman of the Board and Co-Founder

Dr. Edward Rothberg holds a BS in Mathematical and Computational Science, an MS in Computer Science, and a PhD in Computer Science, all from Stanford University. He is Gurobi’s Chief Scientist and Chairman of the Board. He co-founded Gurobi in 2008, served as COO until 2015, and was CEO from 2015 to 2022. Before Gurobi, he led the ILOG CPLEX team. He has more than twenty years of senior leadership in optimization software and has published numerous papers on linear algebra, parallel computing, and mathematical programming. He is a leading expert in sparse Cholesky factorization, computational linear, integer, and quadratic programming, and heuristics for mixed-integer programming.
Zonghao Gu
Chief Research Fellow & Co-Founder

Dr. Zonghao Gu has a B. Eng. in Mechanical Engineering and an M. Eng. in Industrial Management from Tongji University, Shanghai. He has a PhD in Industrial Engineering from the Georgia Institute of Technology. Dr. Gu has published several papers on the computational aspects of mathematical programming. He is one of the world’s leading experts on the computational aspects of linear, integer, and quadratic programming, and is particularly well known for his deep understanding of cutting planes and their application to the solution of general mixed-integer programs. Dr. Gu worked from 1995 to 1998 as an optimization software developer for LINDO Systems, Inc., before joining the ILOG CPLEX R&D team in 1998 as a senior software developer and later as a Distinguished Scientist. From 2005 to 2008 he was Project Architect for the CPLEX R&D team and was the lead developer for CPLEX 11. He was responsible for the implementation of the CPLEX QP simplex and MIQP solvers, had primary responsibility for the presolve and cutting plane routines, and made various contributions to the CPLEX LP simplex solver.
Robert Bixby
Advisor and Co-founder

Dr. Bixby has over thirty years of experience in the optimization software business. Prior to his role as Gurobi CSO, Dr. Bixby held the Gurobi CEO role since co-founding Gurobi in 2008. Prior to Gurobi, Dr. Bixby co-founded CPLEX Optimization, Inc. in 1987. CPLEX was acquired by ILOG, Inc., in 1997, after which he served on the ILOG Board of Directors, was manager of the ILOG CPLEX Development Team, President of the ILOG Technical Advisory Board, and General Manager of ILOG’s Semiconductor Business Division. Dr. Robert Bixby has a BS in Industrial Engineering and Operations Research from the University of California, Berkeley, and a PhD in Operations Research from Cornell University. He has held academic positions at the University of Kentucky, Northwestern University, and Rice University. He is currently Noah Harding Professor Emeritus of Computational and Applied Mathematics at Rice, and Research Professor of Management in Rice’s Jones School of Management. Dr. Bixby has published over fifty journal articles, and is an acknowledged expert on the computational aspects of linear and integer programming. He has won several awards for his work in optimization, including the Beale-Orchard-Hays Prize of the Mathematical Programming Society, and the INFORMS Impact and Frederick W. Lanchester Prizes. In 1997 he was elected to the National Academy of Engineering for his contributions to the theory and practice of optimization.
Tobias Achterberg
Vice President of Research and Development

Dr. Achterberg studied mathematics and computer science at the Technical University of Berlin and the Zuse Institute Berlin. He finished his PhD in mathematics under supervision of Prof. Martin Grötschel in 2007. Dr. Achterberg is the author of SCIP, currently the best academic MIP solver. In addition to numerous publications in scientific journals, he has also received several awards for his dissertation and for SCIP, such as the Beale-Orchard-Hays Prize. From 2006, Dr. Achterberg worked for ILOG/IBM as developer of CPLEX in versions 11 to 12.6. Since 2014 he has been involved as a Senior Developer in the development of the Gurobi Optimizer. In his spare time, Dr. Achterberg likes to play the drums, read books, and play board games. Moreover, he enjoys going to rock and punk rock concerts.
