FRANZ X. VOLLENWEIDER, MD

Director of the Heffter Research Institute, Zürich

Dr. Franz X. Vollenweider is currently the Vice-Director of Research and Teaching and Director of the “Neuropsychopharmacology and Brain Imaging” Research Unit of the University Hospital of Psychiatry Zürich East, and Professor of Psychiatry in the School of Medicine, University of Zürich. He is also the Director of Heffter Research Centre Zürich for Consciousness Studies (HRC-ZH), which he founded in 1998 and incorporated in his research group.

Dr. Vollenweider received his MD degree at the University of Zürich. He completed his doctoral thesis in experimental medicine at the Institute of Toxicology of the University and ETH of Zürich, was trained in neurochemistry at the Brain Research Institute of the University of Zürich, and in neuroimaging at the PET Centre of the PSI-ETH. In 1994 he became certified in the specialities of psychiatry and psychotherapy. His research interests encompass the area of psychopathology, cognitive neuroscience, and behavioural psychopharmacology of psychotic and affective disorders.
Current research focuses on the investigation of the functional networks and transmitter dynamics underlying the experience of self, visual perception, cognitive and emotional processes and the dysfunctions of these processes in human models of psychoses and psychiatric patients. Multiple approaches including measures of information processing, event-related potentials, and brain imaging techniques are used for studying these functions.

Dr. Vollenweider has published over 80 peer-reviewed papers, many of which address the mechanisms of action of psychostimulants, hallucinogens, and entactogens in humans. His research is supported by multiple grants from the Swiss National Science Foundation, the Swiss Federal Health Office, and the Heffter Research Institute (USA), and by multiple AWARDS from the NARSAD and the Fetzer Research Institute USA. He has received the Achievement Award of the Swiss Society of Psychiatry (1990), the Heffter Research Institute Award (1997), the Götz Prize of the University of Zürich (2000), and the British Association of Psychopharmacology Prize (2002).
