The computational progress in linear and mixed integer programming over the last twenty years has been nothing short of remarkable, enabling business, scientific and other applications that literally would have been unapproachable just a few short years ago. The Gurobi founders have been at the forefront of these developments.
The Gurobi team is committed not just to providing the best technology now available, but to continuing to push forward the frontier of optimization solution capability.
Dr. Rothberg has served in senior leadership positions in optimization software companies for more than twenty years. Prior to his role as Gurobi CEO, Dr. Rothberg held the Gurobi COO position since co-founding Gurobi in 2008, and prior to that he led the ILOG CPLEX team.
Dr. Edward Rothberg has a BS in Mathematical and Computational Science from Stanford University, and an MS and PhD in Computer Science, also from Stanford University.
Dr. Rothberg has published numerous papers in the fields of linear algebra, parallel computing, and mathematical programming. He is one of the world's leading experts in sparse Cholesky factorization and computational linear, integer, and quadratic programming. He is particularly well known for his work in parallel sparse matrix factorization, and in heuristics for mixed integer programming.
Dr. Bixby has over twenty 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.
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 currently a Technical Editor for Mathematical Programming Computation. 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.
Mr. Perrucci has 25 years of experience in roles spanning sales, marketing and analytics. Prior to his role at Gurobi, he held the position of CRO at Cambridge Analytica – a predictive analytics firm. Here he built the commercial practice in North America by helping companies drive better advertising through the use of artificial intelligence. Before Cambridge he spent 8 years in martech with FocusVision. Here he built a global sales organization across 6 continents and 10 offices. Prior to FocusVision, Mr. Perrucci spent a total of 9 years at Information Resources Inc. (IRI) working in various analytic consulting roles across the entire PepsiCo enterprise. After the first 4 years at IRI, he decided to gain experience on the brand side and moved into analytics at Unilever. Before long he secured a position in brand management working on the Bertolli business – a $400 million brand in the United States. When IRI came calling again, it was an offer too good to pass up – running the Pepsi Cola and Quaker businesses out of PepsiCo’s world headquarters in Purchase, NY.
Before this journey, Duke earned a BA in Classical Civilization from Fordham University. While en route, he earned his MBA from Cornell University.
Dr. Gregory Glockner has a B.S. magna cum laude from Yale University in Applied Mathematics and Music, and an M.S. and Ph.D. in Operations Research from the Georgia Institute of Technology. His doctoral dissertation was awarded the 1997 Transportation Science Dissertation Prize from INFORMS.
Dr. Glockner has trained users of optimization software in Brazil, Hong Kong, Japan, Singapore, South Korea, and throughout the USA and Canada. He is an expert in optimization modeling and software development: his professional experience in software development includes all major platforms and 9 of the top 10 programming languages in the TIOBE Programming Community Index.
Prior to joining Gurobi Optimization in 2009, Dr. Glockner was partner and Chief Operating Officer for Dwaffler, a provider of decision analysis tools. From 1998-2007, he worked at ILOG in two different positions: as a Senior Technical Account Manager and a Product Manager. As an ILOG Senior Technical Account Manager, he introduced advanced optimization and rules software to customers across North America. As an ILOG Product Manager, he was responsible for product management of CPLEX, ODM, OPL and Solver. From 1997-1998, he worked at Pacific Gas & Electric, where he developed stochastic programming software for hydroelectric power scheduling, and he built statistical tools for energy trading in the deregulated energy market. He has also worked as an operations research analyst for the Federal Aviation Administration and for Northwest Airlines.
Mr. Gundersen is a California-licensed Certified Public Accountant who has spent most of his career leading finance for high-growth VC and PE-backed technology companies. He has taken 3 technology companies through successful acquisitions, most notably as CFO for Rocketmiles (acquired by The Priceline Group in 2015), and as VP Finance for Giftango (acquired by InComm in 2012).
