Richard joined GNS in 2008 upon his return to Aotearoa following 15-years in the United States where he was engaged in Antarctic research. Richard is a glacial stratigrapher and paleoclimatologist, whose work to understand climate change is widely respected in New Zealand and around the world. As well as providing strategic science advice and guidance at GNS, Richard is also a Professor of Geoscience at Victoria University of Wellington. His passion for discovery is evidenced through his leadership of major climate research projects in Antarctica and New Zealand, including the New Zealand SeaRise, Our Changing Coast, and Antarctic Ice Dynamics programmes, which aim to predict the magnitude and impacts of sea level rise on New Zealand communities.

Richard is committed to actively engaging people in science and to that end, he has worked extensively with Maori, iwi, hapu, and whanau on a range of climate-related programmes. His background and interest in education has helped develop projects that support New Zealanders to explore science relevant to their communities.

Richard is also a member of the Melting Ice and Rising Seas team, which was awarded the Prime Minister’s Science Prize in 2020 in recognition of their “transformative scientific discovery or achievement, which has had a significant economic, health, social, and/or environmental impact on New Zealand.”
