Open Early Stage Researcher/PhD 05
Open Early Stage Researcher/PhD Position at Bergische Universität Wuppertal, Germany, and
ST Microelectronics, Italy, as part of
European Innovative Training Network
Reduced Order Modelling, Simulation and Optimization of Coupled systems
ROMSOC is a European Industrial Doctorate (EID) project in the programme Innovative Training
Networks (ITN) and part of Marie Skłodowska Curie Actions within the Horizon 2020 programme.
The ROMSOC EID Network brings together 15 international academic institutions and 11 industry
partners and supports the recruitment of eleven Early Stage Researchers (ESRs). Each
ESR will be working on an individual research project in the host institution with secondments
related to their research in other academic and industrial partners of the network. The research
is focused on three major topics: coupling methods, model reduction methods, and optimization
methods, for industrial applications in well selected areas, such as optical and electronic systems,
economic processes, and materials. The ROMSOC EID Network offers a unique research
environment, where leading academics and innovative industries will integrate ESRs into their
research teams for the training period, providing an excellent structured training programme in
modelling, simulation and optimization of whole products and processes.
We seek excellent open-minded and team-spirited PhD candidates who will get unique international,
interdisciplinary and inter-sectoral training in scientific and transferable skills by distinguished
leaders from academia and industry. Within the ROMSOC network we offer the following
PhD position at Bergische Universität Wuppertal and ST Microelectronics:
Coupling of Model Order Reduction and Multirate Techniques for coupled heterogeneous
time-dependent systems in an industrial optimization flow
Reference number: ROMSOC-ESR05
In industrial circuit and device simulation, e.g. for estimating failure probabilities due to aging,
simulation problems have to be run many times in the loop of an optimization flow. This can only
be done by drastically reducing simulation costs via model order reduction (MOR). This is particularly
challenging in the case of coupled systems when using various simulation packages for
the different subcomponents and physical domains. For efficiency, MOR and multirate error estimates
have to be linked to define overall error estimates, balanced to the accuracy requirements
of the iteration level of the optimization flow.
Consequently, the PhD candiate has to combine advanced concepts of MOR, multirating on
hierarchies of submodels and manifold mapping techniques such that the overall properties of
the system (such as passivity, energy conservation etc.) and stability of the dynamic iteration
process are preserved:
• Generation and analysis of test sets of coupled heterogeneous systems used in the optimization
flow of ST Microelectronics
• New MOR techniques for hierarchies of subcomponent systems preserving stability of dynamic
• Error estimates based on MOR and multirate error estimates allowing for adaptivity of the
• Implementation and validation of software of new techniques for test sets of industrial partner.
The PhD candidate will spend secondments for technical and scientific training at ST Microrelectronics
(Italy). The PhD degree will be awarded by Bergische Universität Wuppertal, Germany.
