About me

I am a geomodeller with Earth Sciences New Zealand (previousl GNS Science) since 2009. My technical role is focused on integrating multi-disciplinary data to create geoscience models that support the sustainable development of geothermal resources in New Zealand and internationally.  I lead the Geothermal Geology and Modelling Team at Earth Sciences NZ.

I have strong governance experience being the Secretary of the New Zealand Geothermal Association (2020-current), the Treasurer of the Asia-Western Pacific Regional Branch (AWPRB) of the IGA (2018-2025) and Executive Secretary of the International Energy Agency Geothermal (IEA Geothermal) (2023-current).

Through these roles, I am well connected internationally and a strong advocate for sustainable geothermal energy utilisation, from low temperature to super hot.
