Bryant has worked on many Australian and international projects aimed at reducing PTSD and other mental health disorders following trauma exposure . These include the 9/11 terrorist attacks in New York , the 2004 Asian tsunami , and Hurricane Katrina . For example , he worked with the Thai Ministry of Health to develop a mental health initiative to manage the effects of the tsunami on mental health . Following Hurricane Katrina he was invited to co-develop a mental health protocol for managing disasters in the USA . Bryant adapted his protocol in the aftermath of the major Black Saturday bushfires in Australia , which government authorities adopted as the mental health response to the disaster . In addition , he served on the American Psychiatric Association 's DSM-5 Working Group on Traumatic Stress Disorders and the World Health Organisation 's ICD-11 Traumatic Stress Advisory Group to develop the new diagnostic definitions of traumatic stress disorders
