I am a seed scientist with interests that span seed physiology, ecology, and technology. My research aims to improve our ability to conserve seeds of wild plant species and to enhance our capacity for ecological restoration.

My research includes studies of seed survival and longevity in conservation seed banks and in the field, the environmental factors that regulate seed dormancy and germination, and the development of seed enhancement techniques to promote seedling establishment.    

Research themes

  • Seed storage physiology and longevity
  • Ecophysiology of seed dormancy and germination
  • Seed persistence and soil seed banks
  • Seed enhancement technologies
  • Restoration ecology

WA has its say about Kings Park

Western Australia has returned a glowing report card to Kings Park via a community survey conducted early in 2020, with clear expectations for the park’s role in conserving the State’s flora and supporting the health of the community in its future management.

Invitation to comment

The Botanic Gardens and Parks Authority is seeking community feedback on the Draft Kings Park and Botanic Garden Management Plan 2021-2025 that will guide park management over the next five years.
