About me

I have been Junior Professor (assistant professor) of Mathematics for Uncertainty Quantification at RWTH's Faculty of Mathematics, Computer Science and Natural Sciences since September 2019. His research focuses on the development of efficient methods for the quantification of uncertainties in mathematical models as well as data-driven modeling.

I am a member of the management board of the newly established Collaborative Research Centre Sparsity and Singular Structures (SFB 1481). Together with Prof. C. Melcher, I am moreover leading the integrated research training group of the SFB 1481.

 

Research Interests

  • Uncertainty quantification for differential equation models
  • Hierarchical sampling methods
  • Monte Carlo methods
  • Bayesian inference
  • Inverse problems
  • Multiscale methods
  • Data-driven modelling
  • Data assimilation
 

Projects

Regularizing neural network classification using random perturbations (2022 - )

Robust data-driven coarse-graining for surrogate modeling (2022 - )

 

Open Positions

In the context of the Collaborative Research Center Sparsity and Singular Structures (SFB 1481), we are currently seeking to fill several PhD and postdoc positions related to the subprojects of the CRC. These research projects fall into the areas of mathematical foundations of machine learning and signal processing, analysis, numerical analysis, optimization, probability theory and algebra. The current call for applications and further details can be found here.
