In this invited course for the Brazilian Family Therapy Congress in June 2016, Prof. Vincenzo Di Nicola will explore the predicament of the therapist facing families when families are facing trauma after the disaster. Using ideas from his model of Cultural Family Therapy (Di Nicola, 1997), his work on trauma with the Harvard Program in Refugee Trauma in Haiti (Mollica, 2008), and his philosophical investigations on trauma, Di Nicola will present a new model of trauma and therapy after trauma with a new concept of change based on Alain Badiou’s philosophy of the Event (2009).
