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 an invited 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).
