Academic Background
Wolfgang Kreuzer studied Technical Mathematics at the Technical University of Vienna. After finishing his Ph.D at the Technical University of Vienna (Diploma 1996: Modelling the Cortical Organ with finite Elements, PhD Thesis: Computer aided analysis of the iterative defect correction with respect to stiff differential equations), he worked at the Institute for Applied and Numerical Mathematics at the TU-Vienna.
From 2004 to 2005, he worked as project employee at a joint project of the Institute for Distributed and Multimedia Systems at the University of Vienna and the Institute for Theoretical Chemistry. Since 2004, he has works at the Acoustics Research Institute of the Austrian Academy of Sciences, where he joined the Physical and Compuational Acoustics group
Current Research
The main focus of his current work lies in applied and numerical mathematics, in particular
- Boundary Element Methods for the Helmholtz Equation
- Development of Numerical Algorithms
- Numerical Simulation of HRTFs
- Propagation of Noise and Vibrations
- Frames in Acoustics: BIOTOP
