Biography
Over my 20-year career, I’ve navigated urban streams, graduated to large rivers, paddled across northern lakes, peatlands, and tundras, and sailed through southern subtropical mangroves. Now, I’m planted in Australian agricultural systems. My ADHD brain thrives on non-linear thinking, connecting seemingly unrelated ideas to drive innovative and creative problem-solving.
As a biogeochemist, I blend ecological and social concepts to enhance agriculture value chains. My mission is to create transparent, trusted traceability solutions that empower consumers and producers to know how their choices contribute to a sustainable agriculture system. I lead the development of evidence-based assurance tools, bringing together research in biogeochemical cycling dynamics, soil health, and sustainable land management practices to digitize agricultural supply chains. Guided by responsible principles, I champion open innovation models for an equitable future.

Current Roles
-
IsotopesAU - Chair
I serve as Chair of IsotopesAU, providing scientific leadership of the national, federated stable isotope data platform. I lead the platform's scientific direction, governance, and delivery, and work with national and international partners to ensure isotope data are interoperable, reusable, and fit for research, government, and industry applications. I represents IsotopesAU in the international OneGeochemistry initiative, contributing to global efforts on geochemical data standardisation, interoperability, and best‑practice data governance. -
Ag2050 - Integration
I provide scientific leadership and integration within the AG2050 program, contributing to work‑package design, scenario development, and Theory of Change activities. My role focuses on translating national‑scale futures into scientifically robust, system‑level representations, with particular emphasis on water, climate, and agricultural system responses that inform modelling, research prioritisation, and program outcomes.
