Andrew Gray
I am a consulting biostatistician at the University of Otago. My goal is to improve the quality of health-related research through enhancing biostatistical aspects of that research. In my role, as well as my own research, I work with researchers at all stages of their projects, from developing and refining their research questions through to publishing and disseminating results.

the d34S values of the juveniles suggest they may have consumed varied protein resources. The sulphur stable isotope ratios indicate there was no discernable marine component in the diet of any of the individuals from Nebira. The stable isotope results are interpreted within a wider context of Papuan
south coast trade and exchange systems in an attempt to understand local interaction in the region.
humans, who arrived around the end of the 13th century AD. Little is known about the nature of human adaptation and
mobility during the initial phase of colonization. We report the results of the isotopic analysis (carbon, nitrogen and strontium) of the oldest prehistoric skeletons discovered in New Zealand to assess diet and migration patterns. The isotope data show that the culturally distinctive burials, Group 1, had similar diets and childhood origins, supporting the assertion that this group was distinct from Group 2/3 and may have been part of the initial colonizing population at the site. The Group 2/3 individuals displayed highly variable diets and likely lived in different regions of the country before their burial at Wairau Bar, supporting the archaeological evidence that people were highly mobile in New Zealand since the initial phase of human settlement.
