About

Scientist ,
National Institute of Water & Atmospheric Research

Summary

I am a Principal Scientist and Freshwater Group Manager at the National Institute of Water and Atmospheric Research (NIWA), New Zealand. I have 20 years of experience in environmental science and management. My areas of expertise are water quality data analysis, water quality monitoring operations and network design, invasive species ecology, river hydrology, groundwater ecology, algal ecology and coral reef ecology (60 scientific papers).
Prior to working at NIWA, I was a research ecologist at the United States Environmental Protection Agency. At NIWA, I have led large, government funded research programmes and numerous consulting projects for Maori tribes, NGOs, local, regional and national agencies, and private industry. I have just completed a 15-month sabbatical at The Nature Conservancy of Hawaii. During that sabbatical, I organised citizen-based water quality monitoring for the island of Maui, and compiled coastal water quality data from islands across the mid-Pacific.
