For twenty years, Simon worked at the points where systems fail, across NHS crisis services, forensic settings, and homelessness outreach. That experience now underpins his research, which examines how fragmented services cause harm and how justice-oriented design can repair them. He developed the Layered Care Model, a framework that moves beyond the dual-diagnosis paradigm and reframes pain as a meaningful, socially situated experience rather than individual pathology. The model integrates trauma, social determinants, and agency to show how care systems can be redesigned to be coherent, humane, and operationally viable.
