About me

I used to be a research assistant and PhD student in the Computer Graphics and Geometry Processing Group at Bielefeld University, Germany. In my final project I worked on shape deformation techniques for evolutionary design optimization, a joint research project with the Honda Research Institute Europe.

Among others, my research interests include shape deformation techniques in both computer graphics and design optimization, mesh generation and optimization for simulation and other downstream applications, as well as software design and engineering for graphics and geometry processing.

In April 2015 I joined Coventor in order to work on mesh generation and geometry processing.
