How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Introduction
I currently works in science communication and outreach, as writer, videographer, consultant and trainer. During my PhD, I was part of the project AUGURY, led by Nicolas Coltice the Laboratoire de Géologie de Lyon (LGLTPE - CNRS / ENS Lyon / Université de Lyon) : http://geologie.ens-lyon.fr/augur/?page_id=300

Thesis
Full-text available
Since its formation, the Earth is slowly cooling. The heat produced by the core and the radioactive decay in the mantle is evacuated toward the surface by convection. The evolving convective structures thereby created control a diversity of surface phenomena such as vertical motion of continents or sea level variation. The study presented here atte...
Article
Reconstructing convective flow in the Earth's mantle is a crucial issue for a diversity of disciplines, from seismology to sedimentology. The common and fundamental limitation of these reconstructions based on geodynamic modelling is the unknown initial conditions. Because of the chaotic nature of convection in the Earth's mantle, errors in initial...
Article
Trace concentrations of Ti in quartz are used to indicate the pressure and temperature conditions of crystallization in the ‘TitaniQ’ geothermobarometer of Thomas et al. (Contrib Miner Petrol 160:743–759, 2010). It utilises the partitioning of Ti into quartz as an indicator of the pressures and/or temperatures of crystal growth. For a given value o...
Article
The concentration of Ti in quartz as an indicator of the temperature conditions of quartz crystallization has gained widespread acceptance since the development of the `TitaniQ' geothermometer of Wark and Watson (2006; Contrib Mineral Petrol 152, 743) and its application in a volcanic context to the Bishop Tuff (Wark et al. 2007; Geology 35, 235)....

EGU 2015 Poster : Reconstructing the 3D structure of the Earth's mantle has been a challenge for geodynamicists for about 40 yr. Although numerical models and computational capabilities have substantially progressed, parameterizations used for modeling convection forced by plate motions are far from being Earth-like. Among the set of parameters, rh...

http://adsabs.harvard.edu/abs/2013AGUFM.T51E2505B Linking mantle convection models with Earth's tectonic history has received considerable attention in recent years: modeling the evolution of supercontinent cycles, predicting present-day mantle structure or improving plate reconstructions. Predictions of future supercontinents are currently being...
