Marco Filippi is a PhD Student in Psychology at the University of Kontanz. His research focuses on transdiagnostic biomarkers underlying psychopathology and cognitive dysfunctions, and the effect of psilocybin-assisted psychotherapy on such biomarkers, with particular focus on mitochondrial functioning. His projects involve therapy-resistant depressed inpatients at the Psychiatric Clinic of Münsterlingen (Switzerland), who are treated with psilocybin-assisted psychotherapy, whose mitochondrial functioning, together with cognitive functioning and psychopathology, is assessed across the treatment course. He is also involved in a project assessing mitochondrial functioning and biomarkers of allostatic load cross-sectionally in psychiatric patients and healthy controls.
