Projects

Since January 2014, I am at FICO, developing and maintaining the Xpress Optimization Suite; leading the Mixed Integer Optimization R&D team since February 2023.
I am a member of the MODAL SynLab. We develop algorithms to solve general mixed integer nonlinear programs and integrate those techniques into state-of-the-art MIP solvers like FICO Xpress.

Before that, I was a member of the Matheon project B20 "Optimization of Gas Transport".
Mathematically, the combination of discrete decisions on the configuration of a gas transport network, the nonlinear equations describing the physics of gas, and the uncertainty in demand and supply yield large-scale and highly complex stochastic mixed-integer nonlinear programs. In this project, we extended the framework SCIP for the solution of nonconvex mixed-integer nonlinear programs.

Further, I was a member of the project "Linear, Integer, and Constraint Programming" at ZIB, and an associated member of the IBM/ZIB Cooperation, the Siemens/ZIB Cooperation, and the Advanced Solver Technology for Supply Chain Management project, a cooperation with SAP and a member of the Matheon project B12 "Symmetries in Integer Programming".
