Overview
I am a psychologist at University of Cologne. I am interested in how people search and integrate probabilistic information and how they learn to do both better. I use artificial neural networks, evidence accumulation models, prospect theory, and other formal models to describe and predict choices, decision times, eye fixations, and other measures.
I give classes on social and cognitive psychology and statistical methods such as cognitive modeling. I am also interested in how to teach practices of Open Science to students.
