Research Fellow
Dr. Teresa Katthagen serves as a Postdoctoral Research Fellow and Psychologist within the Department of Psychiatry and Neurosciences at Charité – University Medicine Berlin's Campus Charité Mitte. Based in Ward 154T and actively contributing to the Research Group Learning and Cognition, her clinical and research activities center on understanding the pathophysiology of schizophrenia and related psychotic disorders through advanced neuroimaging and computational methodologies. Her research program critically examines the neural substrates of motivation deficits (apathy), reward processing abnormalities, and belief formation in psychosis. Utilizing functional MRI, computational modeling of decision-making, and longitudinal study designs, she investigates how striatal-cerebellar circuits, dopamine signaling, and uncertainty processing contribute to symptom dimensions such as negative symptoms and delusions. This work bridges cognitive neuroscience with clinical psychiatry to identify transdiagnostic mechanisms. Recent publication trends demonstrate a sustained focus on schizophrenia spectrum disorders, particularly the computational and neurobiological basis of apathy and negative symptoms. Her work frequently employs fMRI to study striatal prediction error signaling, cerebellar-ventral tegmental area connectivity, and the impact of stress on cognitive flexibility. A notable emphasis exists on methodological rigor through longitudinal designs, multi-site validation, and reproducibility frameworks. Scientific awards and honors were not documented in the provided materials. Details regarding graduate student mentorship and externally funded research grants are not specified in the available information. As a key member of the Learning and Cognition Research Group, Dr. Katthagen collaborates within a multidisciplinary team that integrates computational psychiatry, cognitive neuroscience, and clinical research. The group maintains strong methodological expertise in fMRI data acquisition and analysis, computational modeling of behavioral tasks, and longitudinal study design to advance mechanistic understanding of psychiatric disorders.
