Hendrik Ranocha is a Postdoctoral Fellow in the Cluster of Excellence at the University of Münster, Germany.

His research is focused on the analysis and development of numerical methods for partial and ordinary differential equations. In particular, he is interested in the stability of these schemes as well as mimetic and structure-preserving techniques, allowing the transfer of results from the continuous level to the discrete one.
