Keynote Lecture 1 – Navigating Decision Environments and Adaptive Strategy Selection

Lecturer: Niklas Keller
Fields: Cognitive Science / Decision Making / Machine Learning



The talk will provide the students with an overview of decision environments and the impact they have on the utility of different (heuristic & competence-driven vs statistical or machine learning) approaches to decision making. It will discuss under which conditions simpler strategies can lead to better predictions than modern data-driven technologies and how to foster decision-making competence for an uncertain world.

Dr. Niklas Keller

Dr. Niklas Keller is a research associate at the Clinic for Anesthesiology and Intensive Care Medicine at the Charité University Medicine, Berlin, and an associated scientist at the Max Planck Institute for Human Development, Berlin, as well as the “Decision Engineering and Decision Sciences” lab at the Michigan Technological University. The work and research focus of Niklas Keller lies in the field of organizational psychology, developing methods to support decisions in critical situations, as well as risk communication and defensive decision-making. In cooperation with the German Armed Forces, he developed simple decision support tools to differentiate between civilians and suicide bombers at military checkpoints. In his work at the Charité, he tought medical students and physicians to interpretat and communicate medical statistics and developed tools to improve post-operative patient allocation and patient-handovers.
