Currently she investigates individual differences in side effects to antipsychotic treatment.

Werner Surbeck MD, PhD. Postdoc


Werner studied medicine at the University of Zurich. After his training in neurosurgery, he specialized in epilepsy surgery and functional neurooncology before completing a PhD on the electrophysiological investigation of the insular region. At present, he undergoes additional specialty training in psychiatry and is involved in research projects in the field of brain-based semantic processing abnormalities in schizophrenia spectrum disorders.

Janis Brakowski, MD. Postdoc


Janis is a clinician scientist and is the deputy head of the Center for Acute Psychiatry at the Psychiatric University Hospital Zurich. He studied Medicine at the Charité University Medicine Berlin as well as Philosophy and History at the Humboldt University Berlin. He completed his residency in psychiatry (with Erich Seifritz) at the Psychiatric University Hospital Zurich and at the Department of Neurology of the University Hospital Zurich. His main interest is the analysis of resting state functional connectivity in neuropsychiatric disorders. Currently he investigates functional connectivity of striatal networks and severity of negative symptoms in schizophrenia.

Nils Kallen, MD. Postdoc


Nils studied medicine at the University of Bern. He is currently a resident in psychiatry at the University Hospital of Psychiatry in Zurich and is interested in biomarkers of central system abnormalities that may predict conversion to psychosis in high risk subjects.

Giacomo Cecere, MD. Postdoc


Giacomo was born in Rome, Italy. He received his medical degree from Campus Bio-Medico University of Rome before moving to Switzerland. Giacomo is a third-year psychiatry resident. He has been working at the Zürich University Psychiatry Hospital since 2017.

Rahel Horisberger, MSc. Doctoral student


Rahel studied Clinical Psychology, Biology and Art History at the University of Zurich. She works as a clinical psychologist and psychotherapist at the Psychiatric University Hospital in Zurich. Her current research activity for a dissertation focusses on the assessment and psychotherapeutic treatment of negative symptoms in schizophrenia (in collaboration with Prof. B. Kleim and Prof. S. Kaiser). The development of brief psychotherapeutic interventions for psychotic disorders in the context of acute inpatient treatment forms the extended focus of her research interest.

Stephanie Winkelbeiner, PhD. Postdoc


Stephanie completed her PhD at the University of Bern in 2019 and currently works as a postdoc and psychologist at the University Hospital of Psychiatry. As a clinician researcher, she is interested in the question of whether or not patients respond differently to interventions (antipsychotics, brain stimulation, psychotherapy).

Noemi Dannecker, MSc. Graduate student


Noemi completed her masters in neuropsychology at the University of Zurich and has worked as a neuropsychologist at the University Hospital Zurich. In her PhD project she is going to apply natural language processing, machine learning, and neuroimaging to identify language markers for mental health and mental illness in the psychosis spectrum.
