About

I am a Senior Specalist for Data & AI in the public sector at PD - Berater der öffentlichen Hand GmbH and an independent consultant and trainer for topics related to computational reproducibility, data management, and open science (see my portfolio).

Before, I was a Postdoctoral Research Data Scientist in the Research Group “Cognitive Neuroscience: Mechanisms of Learning and Change” at the University of Hamburg, a Doctoral Researcher at the Max Planck Institute for Human Development, Berlin and a Research Fellow of the Max Planck UCL Centre for Computational Psychiatry and Ageing Research. In my scientific work, I investigated fast neural reactivation of task representations in the human brain using functional magnetic resonance imaging.
