Addiction counts among the most common psychiatric disorders. A complex combination of biological, genetic, epigenetic, social, and psychological factors impacts patients' onset and progress.

Our group investigates various topics from addiction research. We take neurobiological as well as social aspects into consideration, such as stigma or delinquency. In addition to base research questions, we also carry out epidemiological and clinical studies.

Thereby, the focus of our interest is on physical dependencies (Alcohol, Nicotine, Medication, or illegal drugs) as well as psychological dependencies (internet and computer addiction, gambling).

We also cooperate with several departments both inside and outside of Hannover Medical School, such as the Department for Transplantation medicine (related to alcohol-induced liver transplantations), the Institute for Pathology, and the Department for Neurosurgery.

Aims of the research group

The overarching aim of our research is the identification of epigenetic markers for the outcome and course predictions for patients suffering from addiction disorders.
