Research | Current

I am particularly interested in identifying affordable, practical and scalable interventions (appropriate to local conditions and populations) to address the leading non-communicable diseases in New Zealand, namely heart disease, respiratory disease, and cancer. I have built up a sustained, systematic and comprehensive programme of multidisciplinary addiction research, particularly focusing on two leading risk factors for non-communicable diseases - alcohol and tobacco. The research has spanned from preclinical research through to policy. I have published in the fields of tobacco control and smoking cessation (e-cigarettes, cytisine, nicotine reduction, increasing uptake of existing cessation medications, exercise for smoking cessation, hypnotherapy, incentives, smokefree programme evaluations, and smokefree environments) alcohol (mhealth alcohol interventions), other drugs (cannabis, ibogaine) and other addictions (sugar).
