The availability of very large data sets offers new possibilities and challenges for research within** SACS**.

Data-driven science allows the discovery of hidden parameters or functions in dynamical systems from observed data by solving (ill-posed) inverse problems. Also, topics such as uncertainty quantification and model order reduction are rapidly gaining importance. We aim therefore to combine data-driven science with our strong research in dynamical systems, scientific computing, and mathematical systems theory. This will offer new opportunities to obtain more accurate data-driven models in for instance neuroscience, seismic, and turbulence, but also present significant mathematical challenges, such as understanding the mathematical properties of these new models and techniques and deriving and analyzing accurate and efficient numerical discretizations for these novel approaches.

The SACS research team focuses on the following topics in the area of dynamical systems, numerical analysis and scientific computing, and on systems and control, and in particular, their relation with data science.
