Biography

My interest in volcanoes originated during my Ph.D. at École Normale Supérieur in Paris where I worked under the supervision of Prof. Éric Calais and Prof. Michael Ghil. My initial project dealt with the statistical analysis of GNSS time series recorded around volcanic edifices in order to extract relevant volcanic signals hidden by the noise inherent to geodetic data sets. The volcanic signals extracted through the methodology I developed gave me the opportunity to study the temporal evolution of volcanic edifice deformation and the dynamics of volcanic systems.

Education

I obtained a master degree in geophysics in 2014 from the Institut de Physique du Globe de Paris (IPGP). I then did my phd at ENS in Paris, France. I defended my phd on volcanoes dynamics and geodetic time series analysis in 2018.

Professional Experience

I started did my phd at ENS Paris under the supervision of Prof. Éric Calais and Prof. Michael Ghil. I started in 2014 and defended in 2018. I held my first postdoctoral appointment between April 2018 and december 2020 at ENS Lyon in France where I worked with Chloe Michaut on volcanic systems located on the Moon and Mars and associated fracture patterns. I then worked as postdoctoral fellow at Penn State University with Christelle Wauthier from March 2021 to August 2023.

Research Interests

My research focuses primilary on understanding volcanic systems. I mainly focus on the three following topics: (i) the dynamics of volcanoes, (ii) geophysical time series analysis, (iii) and the physics of magma ascent and intrusion emplacement within planetary crust. Overall I systematically lead my research on two complementary fronts : (i) gathering and extracting original information about volcanoes from various datasets and (ii) designing and studying physical models of volcanoes.

Selected Awards

I was awarded a phd fellowship from Paris Science et Lettre (PSL) University in 2014.
