Emergency management

My present research interests include individual risk perception and risk taking, risk adaptation to increased safety margins, risk management within organizations, and training for individual mindfulness and organizational resilience.

Risk compensation

This line of research addresses simulator-based design and evaluation of advanced driver assistance systems (ADAS), with special focus on how drivers perceive risk in vehicles equipped with ADAS.

Biologically-inspired neural networks

This line of research addresses the problem of how to achieve translation-invariance, that is, how to achieve a stable object representation in spite variations in the image. The biologically-based approach is to use local feature detectors in the first step, and then to combine and transform the detected features step-by-step across several stages of processing, in this way building up internal representations that are increasingly invariant with respect to position and size changes in the input image.
