Born and educated in the Netherlands, Cecile came to New Zealand and AgResearch in 1995 and now leads the nitrous oxide (N2O) research team which focuses on developing mitigation strategies for reducing N2O emissions from pastoral soils. As a Principal Investigator at the New Zealand Greenhouse Gas Research Centre (NZAGRC), she also leads the N2O research programme conducted through the NZAGRC.
Cecile is also the Programme Leader for the P21 Research Programme – Environment, a cross-organisation R&D programme focused on the development of farmer-friendly tools and technologies for reducing losses of nitrogen, phosphorus, sediment and faecal indicator organisms to our surface water bodies. In this role, she is working closely with the pastoral industry, in particular DairyNZ, Fonterra and Beef+Lamb NZ, and the collaborating research organisations.
Cecile was the New Zealand representative on an international panel to review the N2O inventory methodology of the Intergovernmental Panel on Climate Change (IPCC), a role for which she was honoured with a copy of the 2007 Nobel Peace prize that was awarded jointly to Al Gore and the IPCC. She is working closely with MAFPolicy in coordinating and conducting national research programmes on N2O emissions from soil to improve New Zealand’s N2O inventory methodology. She currently leads several N2O research programme including one of the four national field trials investigating the effect of nitrification inhibitors on pasture response and N2O emissions.
