Personal profile
Biography
In 2005, I obtained a PhD in Metamorphic Petrology and Geochemistry at the Centre de Recherche en Pétrographie et Géochimie (CRPG) in Nancy (France). My PhD addressed the significance of U-Pb ages in metamorphic zircon from Naxos and Ikaria Islands (Greece).
After completing my PhD, I undertook a part-time lecturer position (teaching only) for one year at the University Henri Poincare (France). I then relocated to Australia where I worked in several institutions before UWA: as a research associate at Macquarie University from 2006 to 2008 and as a post-doctoral fellow at the ANU from 2009 to 2012. During those six years, I have built up substantial experience in experimental petrology applied to subduction zone processes before coming back to working on natural rocks and secondary ion mass spectrometer (SIMS) at the end of my contract at the ANU. Since 2012, I have been working on the AMMRF flagship SIMS CAMECA 1280 at the Centre for Microscopy, Characterisation and Analysis (CMCA) at UWA.
Roles and responsibilities
Since 2019, I have been appointed as a SIMS senior lecturer at CMCA-UWA. My role is to lead the IMS1280 laboratory, which involves research (collaborative, my own projects and analytical development), laboratory management and teaching (technical training and academic).
Research interests
My research interests in metamorphic petrology and geochemistry are:
(i) Understanding mineral textures and element behaviour during microscale processes of mineral growth and re-equilibration. This is the mainspring in working with an in-situ analytical technique like the SIMS Cameca 1280.
(ii) Characterization and temporal evolution of geochemical cycles in subduction zones.
Developping new analytical techniques is at the core of my work in the SIMS lab at UWA either in the frame of collaborations or for my own research.
