## Biography

Felix Tretter graduated in philosophy, psychology, medicine, statistics, sociology, and economics at the universities of Vienna and Munich. Subsequently, he worked as a scholar at the Max-Planck Institute for Psychiatry in Munich. After earning doctorates as Dr. phil., Dr. med. and Dr. rer. pol. he habilitated to qualify as a professor in clinical psychology at the Ludwig-Maximilian University Munich.

Felix Tretter is deputy head of the Bavarian Academy for Addiction and Health Issues (Bayerische Akademie für Sucht- und Gesundheitsfragen). Since 2015 he is fellow at the Bertalanffy Center for the Study of Systems Science (BCSSS) in Vienna.

## Scientific work

Tretter wrote research papers, review articles, and books. The main focus of his scientific work is mathematical description of neuropsychological mechanisms in the evolution of schizophrenia and addiction. He aims at describing psychosocial problems from a perpective of cybernetics, systems and ecology. Additional publications by Tretter include systems biology and theory of medicine applied to different fields, including COVID-19.
