Biographical Sketch

Richard Schussnig, born in 1993 in Rottenmann, Austria, completed his Bachelor’s and Master’s degrees in civil engineering with a focus on structural engineering from Graz University of Technology. He then joined the LEAD Project “Mechanics, Modeling, and Simulation of Aortic Dissection”, a consortium led by Prof. Gerhard A. Holzapfel. This experience sparked his interest in biomechanics, computational engineering, and numerical mathematics. In December 2022, Richard defended his thesis entitled “Generalised Newtonian Fluids in Cardiovascular Fluid–Structure Interaction,” thus receiving his doctorate in civil engineering sciences.

In January 2023, Richard joined the group of Prof. Martin Kronbichler, the principal developer of deal.II and recipient of the 2025 SIAM/ACM Prize in Computational Science and Engineering. Their joint work focuses on high-performance computing in computational medicine, in particular on matrix-free implementations of finite element methods at exascale for cardiovascular applications. Richard joined the group at the University of Augsburg and relocated to Ruhr University Bochum in January 2024, where he remained until September 2025. There, he contributed to the EuroHPC Joint Undertaking project dealii-X: Exascale Framework for Digital Twins of the Human Body as part of the project management team, while also supporting the PDExa project, which focused on optimized software for solving partial differential equations on exascale computing systems.

Richard has been awarded a Marie Skłodowska-Curie Postdoctoral Fellowship by the European Research Council for the “VascularROM” project. This project brings him to the Institute of Biomechanics at Graz University of Technology, starting with an 18-month research stay at the Oden Institute for Computational Engineering and Sciences at the University of Texas at Austin, USA. Under the supervision of Professors Karen Willcox, Thomas J. R. Hughes, and Gerhard A. Holzapfel, the project aims to advance computational medicine by integrating model order reduction and uncertainty quantification techniques with high-performance computing and computational biomechanics of the cardiovascular system.
