Torben heads the Decision Circuits Lab at the Bernstein Center for Computational Neuroscience and Humboldt University of Berlin, Germany. He received his Ph.D. in neuroscience at the Max Planck Research School (Tübingen, Germany) for his work on the neuromodulation of cortical memory processes by dopamine. He went on to conduct research at Cold Spring Harbor Laboratory (NY, USA) and Washington University School of Medicine in St Louis (MO, USA, where he investigated how the brain generates confidence in our perceptions of the world around us. In Berlin, Torben’s lab focuses on understanding how neurochemicals such as dopamine and serotonin influence information processing that shape perception and behavior in both humans and animal models. Using a cross-species computational psychiatry framework, current research projects address the neural mechanisms that underlie serotonergic hallucinations.
