Research field

My research interests are material modelling, homogenization theory, data-supported materials design of multiphase materials, neural networks and objective-oriented model order reduction.

In the field of materials design my aim is, based on (e.g., mechanical, thermo-mechanical, piezomechanical) materials properties prescribed/required by an application, (1) to scan large material databases for potential candidates or combinations and (2) to determine optimal microstructure statistics.

In the field of neural networks, I mainly work in Python with Numpy, Keras and TensorFlow and train the neural networks based on large simulation datasets.

Further, I work on objective-oriented model order reduction techniques, which update a quantity of interest based on suitable function spaces, data-driven surrogate models and error estimates.
