Activities


I am working on Numerical Shape Optimization of Extrusion Dies as a member of the Cluster of Excellence Integrative Production Technology for High Wage Countries.

Besides that, I was the first and second elected President of the SIAM Chapter Aachen in its first two periods from 2014 to 2016 and fostered the connection between Applied Mathematics and the Industry together with a group of motivated doctorate students. The Chapter is healthy and moves towards the future with a new board as I finish my PhD.
