The Chair of Nonlinear Dynamics at the Institute of Mechanical Systems (Prof. G. Haller), ETH Zurich, seeks immediately or by agreement a
Postdoctoral Fellow in the area of Data-Driven Nonlinear Modeling and System-Identification for complex mechanical vibrations
The project aims to develop numerical methods that reconstruct nonlinear features of high-degree-of-freedom mechanical systems from experimentally measured vibration data. The mathematical basis for this effort is the recent theory of spectral submanifolds developed within the Chair of Nonlinear Dynamics (see georgehaller.com/publications/ for more information). The expected result is a numerical package that identifies a low-dimensional model from measured continuum vibrations and constructs nonlinear amplitude- and frequency response curves for the most important mechanical degrees of freedom. The numerical procedure will first need to be validated on data generated by finite-element models, then on experimental data.
The ideal candidate has a a PhD in engineering, applied mathematics, computer science or physics; research interest and background in mechanics and nonlinear dynamics; demonstrated experience with numerical methods (finite-element methods, in particular) and data analysis; interest in a research career and in interdisciplinary project collaboration and working knowledge of English. The contract duration is 1 year, renewable upon satisfactory progress.
