About Troy

Troy Baisden specialises in understanding the flow of nutrients, water and carbon through terrestrial ecosystems and resulting impacts in freshwater. He spent the last decade at GNS Science’s National Isotope Centre, ensuring New Zealand has access to challenging isotope techniques combined with the ‘big-picture’ understanding required to apply them to the nation’s most important environmental issues. This has involved sophisticated instrumental techniques, yet the most crucial understanding often evolves from large scale environmental and economic data, viewed in a policy, social and cultural context. His experience cuts across major environmental issues, starting with acid rain in the United States, and bringing parallels from climate change research to managing water quality in a catchment context.

Troy wants to see science enable innovative approaches to water management that create flexibility, efficiency and resilience. He has an interest in analytics and science policy as they relate to addressing global change issues. He holds a PhD from the Department of Environmental Science, Policy and Management at the University of California, Berkeley. He is also an Investigator in Te Pūnaha Matatini, the Centre of Research Excellence on networks and complexity. He now leads the Lakes Ecosystem Research New Zealand (LERNZ) group.

Troy makes an effort to make the process of putting the pieces of environmental science accessible – check out his articles in The Conversation, and the resources below.
