Niklas Keller

Research Scientist, Charité University Medicine, Berlin

Niklas Keller is a research scientist at the Center for Anaesthesiology and Intensive Care Medicine at the Charité University Medicine, Berlin, and Associate Researcher at the Decision Sciences and Decision Engineering Laboratory, Michigan Technological University.

His research focusses on the design of simple and robust decision aids for use in situations characterized by time pressure, stress, and high stakes (military, police, emergency medical services), designing interventions for the transparent and intuitive communication of risk and uncertainty, as well as assessing and counteracting defensive decision making in organizational contexts. 

Niklas Keller holds a BSc in Psychology, an MSc in International Relations and a PhD in Psychology. He has given lectures and trainings to the German Armed Forces and the Police, and has trained over 1000 medical students and professionals in risk literacy, as well as designed and provided curricular content on risk communication for the medical curriculum for the Charité University Hospital and the University Hospital Heidelberg.
