An Insight

We are delighted to congratulate our NHR Graduate School Fellow, Rostislav-Paul Wilhem, on his incredible accomplishment of completing his doctoral thesis with the highest distinction, summa cum laude, on the topic "Structure-preserving numerical methods for the Vlasov equation without a phase-space mesh." 

The thesis was supervised by Prof. Dr. Manuel Torrilhon and Prof. Dr. Eric Sonnendrücker at the NHR Center of the RWTH Aachen University. 
The NHR-Association provided financial support in the form of a monthly scholarship, opportunities for scientific training and further education as well as access to high-performance computers. 

Rostislav-Paul Wilhelm’s research focused on the fundamental challenges in the numerical solution of the kinetic Vlasov equation for plasmas. He developed a novel approach to overcoming these challenges, showing that the system dynamics can be reconstructed from stored electromagnetic potentials using the Lagrange and Hamilton structure of the Vlasov equation. This results in reduced memory requirements and eliminates a numerical discretization error. Rostislav-Paul Wilhelm's innovative approach to numerical solution of the kinetic Vlasov equation has yielded novel findings that hold immense potential for future advancements in the scientific community. 

Further information on his research as well as the respective code base can be found here. 
We wish Rostislav-Paul Wilhelm continued success in his professional scientific career.

An interesting and intensive program week has come to an end. Our fellows traveled from all NHR centers across Germany and were welcomed in Paderborn by Prof. Christian Plessl, the director of the Paderborn Center for Parallel Computing. The focus of the program week was on various HPC workshops, including e.g. "Julia for High-Performance Computing", “MPI Correctness Checking” and training on” Parallel Neural Networks”. On the last day, our fellows participated in soft skills seminars on "self-presentation" and "anti-bias & intercultural communication". In addition, all participants had the opportunity to present their projects and to get to know and network with each other during various activities. We are already looking forward to the next NHR Summer School!

We would like to thank our trainers of the NHR Summer School 2023: Dr. Xin Wu (PC2), Dr. Carsten Bauer (PC2), Joachim Jenke (RWTH), Alexander Hück (TUDa), Simon Schwitanski (RWTH), Adrian Schmitz (RWTH), Dr. Charlotte Debus (KIT), Dr. Marie Weiel (KIT), David Li (KIT).
