Overview

The research group investigates problems from optimization, optimal control, as well as inverse problems in technological and economic applications. The work covers basic research regarding analysis and numerics, the development of efficient algorithms and software and the solution of application problems. A specific research focus is the investigation of special structures due to uncertain and non-smooth data. In their research, the group touches almost all main application areas of the WIAS and concentrates on the topics

• Stochastic and non-smooth optimization
• High-dimensional parameterized inverse problems
• Optimal control of multifield and multiscale problems

Highlights

We organized the Workshop “Frontiers of Stochastic Optimization and its Applications in Industry” which took place from May 10 - 12, 2023.

The Berlin Study Group with Industry (ESGI 175) took place at WIAS from September 18 to 22, 2023.
