Sorry listeners, a few days late with this one — enjoy!

Elisabeth (Ellie) is a Master student in Geophysics and a Planetary Scientist at the University of British Columbia (UBC), where she studies a landform unique to Mercury called hollows. She focuses on those occurring at impact craters and whether a relationship can be derived between relative crater age and hollow locations within their host craters in order to better understand how hollows form, grow and "die" on Mercury. Ellie completed her undergraduate degree in Geology in France before moving to BC where she can now be found roaming the mountains in her spare time.
