He then joined the Institute of Structural Analysis as a research and university assistant under Prof. Thomas-Peter Fries, working on Modelling and Simulation of Aortic Dissection, a joint project with the Graz Center of Computational Engineering on Mechanics. Within this project, his research focused on the design and application of efficient and accurate finite element schemes for fluid-structure interaction and related subproblems in the context of hemodynamics. In 2022, Richard defended his doctoral thesis on „Generalised Newtonian Fluids in Cardiovascular Fluid-Structure Interaction“, for which he was awarded the Dr.-Klaus-Körper-Preis 2023 and the CEACM Young Researcher Award 2023.

Richard then joined the group of Prof. Martin Kronbichler at University of Augsburg and Ruhr University Bochum as a post-doctoral fellow, continuing his work on numerical methods targeting incompressible (multi-phase) flow, non-Newtonian fluids, hyperelastic tissue models and their application in the medical and engineering context. In February 2025, Richard was awarded a Marie Skłodowska-Curie Post-doctoral Fellowship, which brings him to the Oden Institute at the University of Texas at Austin as a research affiliate postdoctoral, working together with Gerhard A. Holzapfel, Karen Willcox and Thomas J. R. Hughes on model order reduction and digital twins of the vascular system.
