Only a few months after onboarding two new colleagues for technical support and API development, we are excited to announce the addition of a new core mathematical optimization expert to our FICO Xpress Optimization team. Please join us in welcoming our newest member in the MIP Solver development team, aka “Team Gomory”: Dr. Philipp M. Christophel.
Philipp brings extensive expertise in mixed integer optimization solver development with more than 18 years of experience working on commercial products in the field. His deep technical knowledge spans almost all core areas of mixed-integer optimization including presolve, cutting plane separation algorithms, primal heuristics, symmetry handling and MIP-simplex integration.
Beyond his solver development work, Philipp has also supported numerous customers in modeling and solving their mixed integer optimization problems, bringing the customer-focused perspective that we value so much at FICO.
He received his PhD in Operations Research from the Decision Support and Operations Research (DS&OR) Lab at the University of Paderborn, Germany. During his academic journey, he also spent time as a researcher at the Center for Operations Research and Econometrics (CORE) at UC Louvain, Belgium.
Consequently, at FICO, Philipp will do what he is best at: Developing cutting-edge optimization algorithms to contribute to the continuous performance improvements and feature extensions of our FICO Xpress Solver.
Please join us in welcoming Dr. Christophel to the team and follow the FICO Xpress Optimization Blog for new posts.
