BIO.

Frederike is a Senior Scientist at the Translational Neuromodeling Unit (TNU) at the University of Zurich and ETH Zurich.

Before coming to Zurich, Frederike obtained a M. Sc. Hon. Degree in Physics at the University of Würzburg, followed by a PhD in Neuroscience at the Graduate School of Systemic Neurosciences at the LMU Munich and the Bernstein Center for Computational Neuroscience in Munich under the supervision of Prf. Dr. Stefan Glasauer, graduating in 2013.

Her main research focus is the use of computational models to study perception and cognition in health and disease. She is currently one of the organisers of the Computational Psychiatry Course in Zurich.
