Automated Model Discovery for Soft Matter Systems
(Drittmittelfinanzierte Einzelförderung)Project leader: ,
Term: 1. Juli 2024 - 30. Juni 2029
Acronym: DISCOVER
Funding source: EU / European Research CouncilAutomatisierte Modelle bringen Erforschung weicher Materie voran
Weiche Materialien, die sich durch thermische oder mechanische Beanspruchung leicht verformen oder strukturell verändern lassen, sind im modernen Leben unverzichtbar, wobei sie Autonomie, Nachhaltigkeit und Gesundheit beeinflussen. Die genaue Modellierung dieser Materialien ist jedoch komplex und meist nur von wenigen gut ausgebildeten Fachleuten zu bewerkstelligen. Das Ziel des ERC-finanzierten Projekts DISCOVER besteht darin, die konstitutive Modellierung durch automatisierte Modellfindung zugänglicher zu gestalten. Zu den Zielen zählt die Entwicklung neuronaler Netzwerke, die selbstständig die besten Modelle, Parameter und Experimente für verschiedene Systeme der weichen Materie finden. Zudem werden die Forschenden die Leistung des Modells anhand verschiedener Experimente bewerten und bayessche Analysen zur Messung von Unsicherheiten einsetzen. Die automatisierte Modellfindung sollte die Erkundung eines breiten Spektrums von Modellparametern gestatten und Einblicke in Systeme aus weicher Materie bieten, die mit konventionellen Methoden nicht zu realisieren sind.

(Drittmittelfinanzierte Einzelförderung)Project leader:
Term: 1. Mai 2016 - 15. Juli 2022
Funding source: StiftungenThis project contains the establishment of a heart support system as a contractile membrane based on the pericardium to minimize the consequences of severe heart disease and to maintain proper cardiac function. The project is a research cooperation between the Chair of Applied Dynamics and the Pediatric Cardiology at the Friedrich-Alexander-Universität Erlangen-Nürnberg and is funded by the Klaus Tschira Foundation.
The project includes the study of cardiac function under pathological and normal conditions by developing computer models of the heart, which are validated with experimental data of pediatric cardiology of the University of Erlangen Nuremberg. The clinical measurements and experimental data, as well as the simulation model are based on rat hearts. Subsequently, a cardiac support system based on a membrane is to be designed to improve or at least maintain heart function under pathological conditions.
In particular at the Chair of Applied Dynamics, we are focusing on the development of the underlying computational heart model including the anatomy, morphology, electrophysiology and also the fluid-structure interaction to be able to build up the optimized heart support system but also to better understand the function of the heart and thus to predict or early detect cardiac dysfunctions and bring new treatments to the clinic.
