Dr Lystad is a Research Fellow at the Health Outcomes Stream at the Australian Institute of Health Innovation, Faculty of Medicine and Health Sciences, Macquarie University. Dr Lystad is an injury epidemiologist with a particular interest in traumatic brain injury, spinal injury, paediatric trauma, and sports injury. His research is centred around conducting large population-based studies using data linkages of administrative data collections to investigate health outcomes following injury and to guide improvements in health service delivery and health policy.

Recent projects include population-based matched cohort studies investigating mortality risk among adults hospitalised with traumatic brain injury and excess mortality among older adults hospitalised with hip fracture; nationwide trends of sports injury-related hospitalisations in children over a ten-year period; incidence and severity of head injury hospitalisations in children over a ten-year period; and unwarranted clinical variation in the care of children and young people hospitalised for injury in New South Wales.
