I have a cohesive research programme directed at understanding alcohol policy impacts and the effects of alcohol’s harm to others. My vision is to be an international expert in alcohol research that contributes to evidence-based public policy to reduce alcohol harm. Harm to others than the drinker is an aspect of alcohol harm that is under-researched especially given the importance of research on passive smoking for tobacco control policy. This study will quantify harm to others from drinking using the Statistics New Zealand Integrated Data Infrastructure allowing for data linkage to determine the contribution of alcohol to a key area of alcohol’s harm to others –child maltreatment. This study will provide new knowledge about harm that is largely invisible or neglected, provide a more complete picture of the burden of drinking in communities to inform effective alcohol policy decision making and contribute to international efforts to reduce alcohol harm.
