I joined the LSHTM at the beginning of 2011, after working in New Zealand for the last 30 years. I originally trained in biostatistics, before moving over to do a PhD in epidemiological methods. Since the completion of my PhD in epidemiology in 1985 I have been engaged in a wide range of public health research activities. My current research interests focus on epidemiological and biostatistical methods, and their application to studies of non-communicable diseases (NCDs), including occupational and environmental health, asthma, kidney disease and neurological disease. I have a particular interest in global epidemiological studies. I am a Fellow of the Royal Society of New Zealand (FRSNZ) and the Academy of Medical Sciences (FMedSCi) and Past-President of the International Epidemiological Association (IEA).
