Research interests:
Nonlinear Optimization
- Development and analysis of adjoint-based optimization methods
- Development and analysis of new approaches for nonsmooth optimization
- Development of optimization methods for machine learning
Current activities:
TES Optimization for Machine Learning

Algorithmic Differentiation (AD)
= Calculation of derivatives for functions given as computer programs
I work on
- the maintance and development of our AD tool ADOL-C
- checkpointing techniques
Further information on algorithmic differentiation can be found here. A standard reference is this book.
Research seminar together with the group of Prof. Hante
