Researcher biography

I lead the Carbon & Climate Change Group in the Centre for Environmental Responsibility in Mining.

My research to date has focused on:

  • The role of weathering of serpentinites and other ultramafic rocks in the global carbon cycle
  • Development of carbon offset projects for mining companies, including reforestation, enhanced rock weathering, and carbon mineralisation projects
  • Sourcing feedstocks for reaction with carbon dioxide
  • Carbon accounting at mine sites, with a focus on accounting for land-use change emissions
  • Environmental impacts of nickel mining, particularly laterite deposits
  • Exploration and mining of marine placer deposits, including diamond, gold, and platinum‑group‑element deposits
  • Geochemical and mineralogical tools for mineral exploration, for both traditional commodities and feedstocks for reaction with carbon dioxide

I joined the Sustainable Minerals Institute in 2026 after 14 years working in the mining industry in both geology and sustainability roles, including working as a Climate Change Specialist for the De Beers Group and a Carbon Mitigation Principal for Anglo American.

I have worked on mining and mineral exploration projects on four continents: North America, South America, Africa, and Australia. During my Ph.D. studies, I conducted fieldwork in the Sultanate of Oman in the Middle East.

In addition to my academic research, I am a writer and enjoy writing about science for a general audience. I wrote a geology blog for the American Geophysical Union for several years, and my book Rocks & Minerals: An Illustrated Field Guide was published by Cider Mill Press (an imprint of HarperCollins) in 2023.
