The aim of this Advanced Seminar is to draw together insights from phenomenological psychopathology and values-based practice to promote the co-creation of models in mental health care through the contribution of people with lived experiences of mental illness and other mental health challenges. In focusing on the concept of lived experience, sometimes referred to as ‘Expertise by Experience” (or EbE) in the mental health research literature,  aim to explore crossroads of experiences as the result of a dialogue among experts by training (mental health professionals, researchers, social and mental health workers, etc.) and experts by experience, in light of a new consideration of the cardinal role of personalisation in contemporary mental health care.
