Mark began his professional journey as a researcher at Te Papa Tongarewa, contributing to research as diverse as Ross Sea bycatch and freshwater biodiversity. He holds a MSc from Te Herenga Waka—Victoria University of Wellington, specialising in marine and freshwater ecology and the integration of mātauranga Māori with Western science.
Mark’s research centres on kākahi (freshwater mussels), combining ecological, cultural, and genetic approaches to support their conservation. His genetic studies have contributed to the discovery and description of new kākahi species in Aotearoa, reshaping understanding of their diversity and distribution. This work underpins strategies for their long-term protection and for strengthening connections between kākahi and the freshwater ecosystems they sustain.
Mark is an aquatic ecologist with Earth Sciences New Zealand where he has worked since 2008. Alongside his research, Mark serves on several iwi-affiliated trusts, contributing to kaupapa that uphold the health and cultural values of marine and freshwater environments.
