Postdoctoral Associate

Constraining the evolution of the magnetic field of terrestrial bodies has important implications concerning the evolution of their thermal state, composition, atmosphere, climate and ultimately of their habitability over geological times. Rocks are instrumental in enabling us to track this evolution because they record it through their property of acquiring and preserving magnetization. Deciphering rocks’ magnetic record relies on the acquisition, processing and interpretation of spacecraft magnetic field measurements on the one hand and laboratory measurements of rock samples on the other.

During my work as a PhD student at IPGP in Paris, France and as a postdoctoral researcher at GFZ in Potsdam, Germany I became familiar with the possibilities, challenges and constrains involved in using spacecraft measurements to this end. My desire to expand my skill set and work directly with magnetized samples has led me to the Paleomagnetism Lab at MIT in December 2019, initially as a postdoctoral Marie Sklodowska-Curie Global Fellow. My work here focuses on constraining the evolution of the Martian and lunar magnetic fields. For this, I use magnetic field measurements obtained by spacecrafts and I perform laboratory measurements on Martian meteorites and lunar rocks.
