Julien Bodart is a graduate student in geophysics at the University of Edinburgh. His interests lie in the evolution of ice sheets in response to long-term changes in climatic conditions. As a member of the GHOST team, Julien will be conducting fieldwork on Thwaites Glacier using ground-penetrating radar to sound its subsurface conditions, and use the internal layers found within the ice to reconstruct past changes in velocity and accumulation rates.
