Over the last 20 years, Rizzo has conducted research on the design, development and evaluation of Virtual Reality systems targeting the areas of clinical assessment, treatment and rehabilitation across the domains of psychological, cognitive and motor functioning in both healthy and clinical populations. This work has focused on PTSD, TBI, Autism, ADHD, Alzheimer’s disease, stroke and other clinical conditions. In spite of the diversity of these clinical R&D areas, the common thread that drives all of his work with digital technologies involves the study of how interactive and immersive Virtual Reality simulations can be usefully applied to address human healthcare needs beyond what is possible with traditional 20th Century tools and methods. In his spare time, he plays rugby, listens to music, rides his motorcycle and thinks about new ways that VR can have a positive impact on clinical care by dragging the field of psychology, kickin’ and screamin’ into the 21st Century.
