Mahina-a-rangi Baker
Te Ātiawa, Ngāti Raukawa ki te tonga, Ngāti Toarangatira
 Mahina-a-rangi is passionate about enabling mana whenua involvement in environmental decision-making and supporting kaitiakitanga, particularly around relationships with freshwater catchments. She has a background in kaupapa Māori research and environmental risk analysis and is due to submit a PhD in Resource and Environmental Planning on mātauranga Māori quantitative modelling. Mahina-a-rangi runs a small environmental consultancy managing a team of team of Māori scientists and resource management experts to deliver support to iwi and hapū entities. She is currently Pou Takawaenga Taiao, Environment Manager for Te Ātiawa ki Whakarongotai. She is also a member of the Kahui Wai Māori, a forum that provides independent advice to the government on freshwater management policy development. Mahina-a-rangi will talk about her work developing and operationalising a mātauranga Māori framework and futuring tools, including Bayesian Belief Networks, that indigenous communities can apply in decision-making, including risk analysis processes. The case studies in which this framework and tools were operationalised will demonstrate a distinctly Māori scientific approach to futuring, including the analysis of risk, in various decision-making contexts including catchment management and resource consenting of significant construction projects.
Roger Cook

Roger Cooke
 Roger Cooke is the Chauncey Starr Senior Fellow at Resources for Future in Washington and an emeritus professor at TU Delft. He supervised the development of Non-Parametric continuous-discrete Bayesian Networks (NPBNs) for the Dutch Ministry of Transport. Subsequent development was under contract with Shell, AIRBUS and the National Institute for Aerospace. In 2008 he was elected fellow of the Society for Risk Analysis. Roger Cooke is the patron and greatest endorser of the Classical Model, which is frequently referred to as the Cooke's method for structured expert judgment. His short course on Expert Judgment has been given several times at NASA Langley and NASA Headquarters. In 2010 he was named lead author in the 5th assessment of the Intergovernmental Panel on Climate Change for the chapter on Risk and Uncertainty. In 2011 he received the Lifetime Distinguished Achievement Award from the Society for Risk Analysis. He currently works on uncertainty quantification in conceptual design for AIRBUS and on value of information of Earth Observation Missions for NASA Langley. He consults for expert judgment studies on invasive species (NOAA), food borne diseases (WHO) and efficacy of public health measures (Robert Wood Johnson, CDDEP) and nitrogen loading in the Chesapeake bay (EPA).

Roger will be joining us by video conference to present results from a recent analysis of 49 post 2006 Structured Expert Judgment studies where experts assessed a median value in addition to other percentiles of their distributions for unknown variables and calibration variables. The results show that prediction errors are substantially reduced by combining experts’ quantified uncertainties rather than combing their point predictions. As a consequence, Roger and co-authors conclude that two tenants of decision science folklore are decisively refuted: (1) If we are just interested in point prediction we needn’t quantify uncertainty and (2) combining medians is as good as medians of combinations. 

Nick Golledge
Nick Golledge
Nick is an Associate Professor in the Antarctic Research Centre, Victoria University of Wellington, specialising in the numerical simulation of the Greenland and Antarctic ice sheets, and particularly, their response to changing external forcings over time. Recent work has focused largely on policy-relevant timescales and societally-relevant questions such as the future ice-sheet contribution to global mean sea level. Entwined with this is the role that systemic feedbacks between ice sheets, ocean, and climate, might play in influencing future ice sheet evolution and the manifestation of future climatic changes. Nick currently holds a Royal Society Te Aparangi Discovery Fellowship, is a Lead Author on the Sixth Assessment Report of the IPCC, and leads the 'Future Projections' Expert Group of the Antarctic Science Platform.
