Professor Brenn works on the fields of multiphase flows and rheology. Based on analytical and experimental methods, techniques for characterising rheological properties of viscoelastic liquids are developed. An emphasis lies on elongational rheometry.

This includes the so-called Trefftz methods, with specially focus on the Wave Based Method for plate vibration problems, and the Numerical Assembly Technique for one-dimensional problems like beam vibrations and rotor dynamics. Another research interest is the combination of these efficient methods to build a virtual twin of electrical machines
Dr. Marussig received his PhD in Engineering Sciences from TU Graz. Before joining GCCE, he was part of the Institute for Computational Engineering and Sciences (ICES) at the University of Austin at Texas, USA. Since 2019, he is an assistant professor at the Institute of Applied Mechanics. In his research, he studies the interaction of computational engineering and computer aided design (CAD). He focuses on the development of techniques that enable a seamless integration of complex CAD models into higher-order accurate computer simulations.
Dr. Ceyhun Özdemir received his PhD in numerical analysis, where he considered a coupling of the finite element method and the boundary element method in time domain for the wave equation.

Professor Schanz investigates in his research the numerical simulations of waves in elastic and poroelastic media. Thereby, boundary element methods in time domain are his preferred methods.

The research topics of Professor Steinbach are in the numerical analysis boundary and finite element methods for the approximate solution of partial differential equations. This also includes domain decomposition methods to couple different physical models and discretizations, and the construction of parallel solution methods. Moreover, he considers applications in engineering and industry.
Professor von der Linden works in the field of theoretical and computational physics with emphasize on strongly interacting quantum many-body systems in and out of equilibrium. He is particularly interested in the theoretical description of novel materials, that consist of different coupled degrees of freedom. Such systems result in multi-scale problems, due to the different time scales of the constituents. He also investigates the application of probability theory to data analysis and inverse problems.
