Personal profile

Research interests

My primary field of research focuses on understanding terrestrial and martian volatile cycles during magmatic degassing and mantle dynamics using geochemical tracers such as the noble gases and halogens.

Key Words: Noble gas, halogen, volcanology, magma degassing, mantle, martian meteorite

Following a BSc in Earth Sciences and MSc in Geochemistry (Major) at the Université Paris-Diderot (France), I undertook my Ph.D. in 2008 with Prof. Manuel Moreira at Institut de Physique du Globe de Paris. My Ph.D. research focused on understanding magmatic degassing of volcanic systems during both active and quiescent periods, using noble gases as geochemical tracers. I have studied noble gases in various media including: volcanic rocks, thermal springs and fumarolic gases emitted from active volcanic centres.

From January 2012 to June 2014, I was a post-doctoral research associate working with Prof. Chris Ballentine (Uni. of Oxford) and Prof. Ray Burgess (Uni. of Manchester). I was a member of the ERC funded NOBLE project to improve our current knowledge about halogens (Cl, Br, I) in terrestrial systems and to understand the global volatile cycles in the Earth. I have measured halogens in “fully characterized” basalt glass samples from the Atlantic, Pacific and Indian oceans and these results are currently being prepared for publication. I performed the analyses of ~80 samples using the Neutron Irradiation technique developed in Manchester. During this period of time, I have also commissioned a new noble gas system (Argus VI, ©Thermofisher) in order to measure irradiated samples, improving the detection limits 10-fold both in precision and sensitivity.

Since July 2015, I am working on a STFC project with Prof. Ray Burgess. The aim of this project is to characterise the volatiles, through noble gases and halogen tracers, in Martian reservoirs (mantle, crust and atmosphere), using data obtained from martian meteorites.
