Hello! My name is Margaret!
I am currently a PhD candidate at Purdue University working with Dr. Briony Horgan, and a student collaborator for the Mastcam-Z instrument on NASA’s Mars 2020 Perseverance rover! I’m interested in analyzing and understanding planetary climate history, composition, and surface processes using remote sensing and geologic mapping techniques. I am a recipient of NASA’s 2025 Future Investigators in NASA Earth and Space Science and Technology (FINESST) award in Planetary Science and Zonta International’s 2024 Amelia Earhart Fellowship. For more information on my research projects on Venus and Mars, please check out my research page, or keep scrolling to see my list of publications!
Fun Fact: I’ve made it a personal goal to visit as many craters as possible – I’m currently at six (or seven if you count my adventures operating NASA’s Mars 2020 Perseverance rover at Jezero crater!)
Brent Crater, Ontario, Canada
Meteor Crater, Arizona, USA
Kentland Crater, Indiana, USA
Gardnos Crater, Buskerud, Norway
Santa Fe Impact Structure, New Mexico, USA
Nördlinger Ries Crater, Germany
