Aidan oversees WAVE’s Self-healing Trauma-informed Communities (STiC) work, supporting community-led and statutory projects across the UK. He was the principal researcher in our 3-year study of severe disadvantage which identified the key role of adverse childhood experiences (ACEs) on the pathway to homelessness, unemployment, school exclusion, mental health problems and the criminal justice system; and in a recent project which involved interviewing more than 70 practitioners across education, health, housing and policing UK-wide about trauma-informed practice.
