Ross is Professor of Population Health at the University of Waikato and Population Advisor, Strategy, Investment and Transformation, Waikato District Health Board. He is a Board member for PHARMAC.
Ross was originally a General Practitioner in Wairoa before moving to the Waikato where he trained as a public health physician.
From 2005 he worked for the University of Auckland before joining the University of Waikato in 2016. His research has been on improving health care outcomes through primary care. He has undertaken research in diabetes, cardiovascular disease and cancer – publishing more than 200 papers
My teaching activities include teaching at undergraduate and postgraduate levels, course development and course management.
HELTH201-21A - Epidemiology and Bio-statistics
In trimester A I taught an undergraduate paper to provide students with basic understanding of the techniques and uses of epidemiology in preventing poor health, health planning and evaluation. The course will introduce students to basic epidemiological and statistical methods and how these are applied. A particular focus will be the role of epidemiology in the New Zealand context, and the application of epidemiological principles to support health equity for Māori, Pacific and other population groups.
I have taught undergraduate medical students for more than 20 year at Charing Cross, Imperial College and the University of Auckland. At the University of Waikato I have taught into the Population Health and Sociology programs.
I have regularly supervised research students at honours, masters and doctoral levels. I am currently supervising 2 Foxley Fellowships and 3 PhD students.

With a background in general practice, public health and epidemiology my research interests are focussed on the interface between general practice and specialist health care. I have a track record in using large general practice data sets initially in the field of pharmaco-epidemiology, then in the field of chronic disease management (diabetes, cardiovascular disease and thyroid disease) and over the last ten years I have principally been involved in research into cancer outcomes and the role of primary care in cancer. This has included research into prostate cancer, breast cancer and more recently colorectal and lung cancer. I am a member the Ca-PRI network (The Cancer and Primary Care Research International Network) and a scientific advisor to PC4 (The Primary Care Collaborative Cancer Clinical Trials Group). Much of my research has been in the field of health equity – particularly trying to better understand the drivers of inequity for Māori. I have many years’ experience in working with Māori organisations and I have extensive links throughout the region and further afield. We have also researched inequities for rural populations and Pacific peoples. My research team uses a range of methodologies and is a very interdisciplinary group with expertise in statistics, health economics, qualitative research and kaupapa Māori methodologies. We also have extensive links with clinical teams including specialist surgeons, physicians and oncologists within Waikato and the wider Midland Region. We have active research links with the University of Auckland, the University of Otago and AUT and internationally with the University of Melbourne and Edinburgh. Our medical research group’s aim is to support clinical research with our key partner Waikato DHB. This includes our research into cancer, cardiovascular research (led by Professor Adam El Gamel), and diabetes research led by Dr Lynne Chepulis and Dr Ryan Paul. My group have published more than 50 peer reviewed publications since joining the University of Waikato and have brought in almost $4 million dollars of research funding. (see appendices: research publications and grants).
I have been a regular reviewer for a number of journals over the last six years including cancer journals such as the BMC Cancer, BMC Urology, British Journal of Cancer, Lancet Oncology, International Journal of Urology and Oncotarget and a number of primary care journals including the British Journal of General Practice, Family Practice, British Medical Journal, BMC Family Practice Journal etc.
