Tensor-Galerkin POD for Efficient Uncertainty Quantification in PDEs with Multivariate Random Parameters
Abstract The statistically sound treatment of modelled uncertainties in simulations comes with significant additional computational costs. Since a deterministic model can already be arbitrarily complex, running statistics for general problems may soon become infeasible unless some kind of model reduction is involved.

Mathematical modeling of infectious disease
Abstract Within the last couple of months, the COVID-19 epidemic has determined our public and private life with travel restrictions, lockdown, social distancing, working from home, hygiene rules etc. The daily news informed about reproduction rates and the numbers of current confirmed COVID-19 cases.

Talk: Stability Analysis of Time Stepping Schemes for Incompressible Flows from a DAE Perspective
We consider the time discretization of the semi-discrete incompressible Navier-Stokes equations (NSE) $ \begin{aligned} \quad \quad \quad M \dot v(t) &= N(v(t)) + J^Tp(t) + f(t), \\\\\\\\ 0 &= Jv(t), \end{aligned} $
