Dr Alison Collins – Kaitohutohu Mātanga Pūtaiao Matuaphoto of Dr Alison Collins

Alison, intrigued from an early age about how the world works, studied soil science (the mysterious universe beneath our feet) and geomorphology (how landscapes evolve). Seeing many different soils and landscapes became a passion and took her on a journey from the UK, around Europe and into Mississippi before landing almost 15 years ago in Aotearoa New Zealand.

Alison spent 12 years working for Manaaki Whenua - Landcare Research, leading a portfolio of science around ecosystems, soils, land use and informatics. During her time with Manaaki Whenua, Alison worked with regional councils and central government agencies to understand and prioritise their science needs. She also worked with the science community to find ways in which to facilitate better uptake and use of science. In this capacity she established and became director of a centre for integrating data and science-based tools, facilitating clear and engaging communication.

Alison joined MfE in August 2017 as Departmental Chief Science Advisor.  Still passionate about enabling wise use of science, her role is focused on ensuring ‘valued and trusted science for environmental stewardship’. On a day-to-day basis this means translating complex science, helping to navigating the science system so decision-makers can better access and use the excellent research being done, and building capability at the science to policy interface.
