Academic background

Lucy completed her undergraduate degree in Horticulture at the University of Western Australia and it was during her 4th year project in 2003 that she developed an interest in seed ecology and mine rehabilitation. After graduating with first class honours, Lucy worked as a research assistant with the Seed Science team in the Science Directorate at BGPA for 12 months then commenced her PhD project with the Restoration Ecology and Seed Biology groups. The project combined her fascination with Australian seed germination and dormancy with her interest in applied research and desire to produce practical findings for improving restoration techniques. After completing her PhD in 2008, she continued her research into seed germination and dormancy for mine restoration through projects with Telfer Gold Mine and Rio Tinto Iron Ore in the Pilbara region of Western Australia.

Currently, Lucy is undertaking research with Dr Luis Merino Martin on restoration of a Threatened Ecological Community. This project, based at an iron-ore mine at Koolanooka Hills in the mid-west, combines Lucy’s expertise in seed ecology with Luis’ interest in ecohydrology.

Lucy is passionate about improving restoration through efficient seed use, including optimising seed quality and storage, and understanding germination cues and dormancy mechanisms. Lucy is also interested in arid-zone ecology, seed ecology and seedling recruitment, seed persistence in restoration, and smoke-stimulated germination. Current areas of research include the interaction between loss of physiological dormancy and karrikinolide (an active component of smoke); identifying soil properties and seed germination traits that influence seedling emergence in reconstructed soils; and seed ecology of riparian trees.
