BSc, PGDipSc (Distinction), PhD


I am a vaccinologist, associate professor in the Department of General Practice and Primary Health Care, and the Director of the Vaccine Datalink and Research Group. Since 1998 I have been involved in immunisation-related research in New Zealand including clinical, social science, epidemiological and health systems. My main research areas are vaccine safety and vaccine effectiveness and currently I am co-leading the Global Vaccine Data Network, a multinational consortium dedicated to collaboration in vaccine safety studies. I am a media spokesperson on vaccines and vaccination, science communicator, and teach undergrad and post grad courses.

My research interests include vaccine effectiveness and vaccine safety. I am the chair of the World Health Organization Global Advisory Committee on Vaccine Safety (GACVS) and elected member of the International Brighton Collaboration Science Board.
