Job title: 

Useful Plants Project Research Coordinator

Department: 
Seed Conservation
Section: 
Collecting and Network Support
Joined Kew: 

2013

Foreign languages:

Qualifications and appointments: 
  • Undergraduate Studies, Natural Sciences, University of Cagliari, Cagliari, Italy, 2002
  • PhD, Environmental and Applied Botany, University of Cagliari, Cagliari, Italy, 2009
  • Postdoc Research Fellowship, University of Cagliari, Cagliari, 2009-2013
  • Kew Honorary Visiting Research Associate, 2011
     
Role: 

Provide scientific guidance to partners in country in order to deliver the scientific components of UPP, liaising partners research activities in country with Kew’s scientists involved in the project. Overall responsibility for the production of species profiles for the UPP book. Contribute to the UPP database, through the provision of information and data derived from the production of the UPP book. Support the production of dissemination and promotional material, including species technical information sheets, leaflets and project WebPages. In addition, I interact with the research group on their Science-Americas projects.

During my PhD program and the consequent research fellowship at the University of Cagliari, I investigated the seed dormancy and germination ecology of some of the most threatened endemic species of Sardinia. The results of these studies provided new scientific insights on the autoecology of these species, highlighted possible shifts in their regeneration patterns in response to climate change and have activated ex situ conservation programs for these rare and threatened species. As a Kew visiting Honorary Research Associate, my studies focused on the role of seed dormancy classes on distribution patterns of rare species, on modelling the kinetics of temperature-induced dormancy-loss for these species and understand the possible shifts in regeneration patterns in response to climate change.
