Dr Yannan Jiang


Profile Image
Senior Research Fellow


I gained the first degree in Mathematics from Beijing Normal University, and completed my MSc and PhD degrees in Statistics at the University of Auckland in 2004. A major focus of my research is designing innovative intervention trials to improve population health in New Zealand and other countries.  In 2005, I joined the National Institute for Health Innovation (formerly Clinical Trials Research Unit) in the School of Population Health. As the Senior Biostatistician and Study Co-investigator in their research programmes, I lead in trial design, statistical methodology, data analysis and reports across a wide range of clinical studies. I am the named co-investigator in a number of national and international research projects led by the Liggins Institute, and have worked collaboratively with Conectus on their national studies.

I am a Senior Statistical Consultant of the Statistical Consulting Centre in the Department of Statistics from its inception in 2009, providing consultancy to external clients across a wide variety of statistical services including advice on study design, data monitoring, statistical analysis and reporting, and expert review. In 2012 I was elected to membership of the International Statistical Institute (ISI). I am the statistical reviewer for The Lancet and other medical journals, and also a member of the New Zealand Statistical Association (NZSA) and the Society for Clinical Trials (SCT).

Research | Current

As an academic researcher, I have played a leading role in developing strong relationships with statisticians and researchers within the area of health research in China. In 2008 I successfully organized a symposium in Beijing with support from the New Zealand Vice Chancellors Strategic Development Grant. This activity has initiated and promoted the collaborations between the School of Public Health in Peking University Health Science Centre (PUHSC), and the School of Population Health in The University of Auckland. A number of academic visits have been made with a collaborative research project successfully funded by the China Medical Board.

My current research areas include nutrition and physical activity, smoking cessation, cluster randomized trial design, national survey design and analysis, Phase II/III drug trials, longitudinal and case-control studies with response-selective sampling and missing data problems.

Teaching | Current

I have made constant contributions to the teaching of postgraduate courses and the supervision of student projects and theses, at both the Faculty of Science and the Faculty of Medical & Health Sciences.
