Research Interests

I currently specialise in the integration of remote sensing-based water attributes and hydrodynamic ecologically coupled modelling of water quality and temperature, with a focus on lake monitoring and restoration.

I am currently involved in two smart idea research programmes:

  • Eye on lakes: national monitoring of cyanobacterial blooms. My role in this project includes investigating remote sensing of cyanobacteria.
  • Freshwater bioremediation using native mussels (kāeo) - focussed on shallow eutrophic lakes. My role in this project includes numerical modelling of mussel contributions to lake ecology.

In addition, I work under the Rotorua Lakes Chair, supporting modelling and remote sensing of water quality.

Current international collaboration includes running New Zealand lake model simulations (Lake Rotorua and Lake Tarawera) as part of the Impact Model Inter-Sectoral Inter-comparison Project ( The ISIMIP project provides climate scenarios from global climate model that can serve as inputs to lake model simulations. The first phase of this project will be to evaluate the effects of climate change on global lake thermal stratification.
