EID ROMSOC: Coupling of Model Order Reduction and Multirate Techniques for coupled heterogeneous time-dependent systems in an industrial optimization flow

My name is Marcus Bannenberg and I’m a second year PhD student in the ROMSOC European Industrial Doctorate program which is part of the Marie Skłodowska-Curie Actions (MSCA). I received both my Bachelor’s and Master’s degree in Mathematics from Utrecht University in my home country, the Netherlands. My research project is a joint operation between the Bergische Universität Wuppertal and STMicroelectronics in Catania and is focussed on the combination of model order reduction and multirate time integration.

Why I choose for a Marie Skłodowska-Curie fellowship
In the last year of my Master’s degree I took part in an exchange with the University of Queensland in Brisbane, Australia. Moving out of my comfort zone and discovering a bit more of the world really resonated with me. Therefore, when I decided to pursue a PhD in Mathematics, I knew I wanted incorporate this into my PhD experience. I found this in the MSCA that encourages researcher mobility whilst also combining academic research with industry applications.

What I will do during my PhD
As a researcher I work on the combination of two mathematical techniques and apply it in the industrial optimisation flow of STMicroelectronics. Therefore, my academic work takes place mostly at the Bergische Universität Wuppertal. The implementation of these new algorithms is done on site at the factory of STMicroelectronics in Catania. The goal of the project is to create a reduced order multirate method to decrease the computation effort needed to simulate microchips. To this end numerical analysis has to be done on these methods and practical benchmark cases have to be made.
