I am not working at MathCCES anymore. If you have any questions concerning my research, please contact me via e-mail.

I graduated in Computational Engineering Science (RWTH Aachen University) and achieved a Ph.D. degree in mathematics under the supervision of Prof. Dr. Manuel Torrilhon. Among different topics in applied math and (computational) physics, I am particularly interested in
