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 economic data, viewed in a policy, social and cultural context. Troy wants to see science enable innovative approaches to water management that create flexibility and efficiency beyond what conventional environmental regulation offers. 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.
