Dr. Ali M. Bramson, Principal Investigator/Associate Professor

Ali uses remote sensing observations, such as those acquired with radar and imaging systems onboard spacecraft, to understand the geomorphological and geophysical characteristics of planets. She often combines observational analyses with theoretical modeling, as well as occasional field work at terrestrial analog sites and experimental studies. She is on the team of NASA's Lunar Reconnaissance Orbiter (Co-I for the Mini-RF instrument) and is involved in the science team for NASA's Mars Reconnaissance Orbiter. She works with spacecraft operations to target sites for new data acquisition and is involved in activities that are shaping the future of human exploration on Mars and the Moon. She also develops new instruments and missions for robotic spacecraft missions across the Solar System, frequently working with NASA and its partners at space agencies around the world.

Santa Lucía Pérez Cortés, Graduate Student

Santa Lucía Pérez Cortés received her BS in Geology from the University of Puerto Rico-Mayaguez Campus in June 2022. During her undergraduate studies, she worked on research related to eolian geomorphology on Mars. Currently, Santa is focused on studying features related to mass wasting, impact ejecta, and tectonics on planetary bodies across the Solar System. She enjoys hiking, reading, and warm weather.

Sam Harris, Graduate Student

Sam Harris earned his B.S. in Geosciences in 2024 from Florida Atlantic University where he worked on projects using radar to characterize biogenic gas production within peatlands. At Purdue, Sam is interested in using radar and modeling radar data to better understand subsurface features on the Earth, Moon, and Mars. Outside of research, he enjoys playing jazz (brass and guitar) and playing basketball.

Laura Sofia Pérez Mancipe, Undergraduate Researcher

Laura is an undergraduate student at Universidad de los Andes in Bogotá, Colombia, pursuing a double major in Physics and Geosciences. She first joined the group as part of the Colombia Purdue Partnership and Purdue’s Summer Undergraduate Research Fellowship (SURF) program and has stayed on for her senior thesis. She is researching the evolution of icy scarps in the Martian mid-latitudes, investigating how sublimation-driven processes shape scarp morphology and ridge formation. Her work specifically focuses on understanding the ages of the ridges present in Martian scarps and how their morphology varies between the northern and southern hemispheres.

Isabella Shockley, Undergraduate Researcher

Bella is a Planetary Sciences and Aeronautical & Astronautical Engineering double major at Purdue. She is investigating surface and shallow subsurface properties in the South Pole–Aitken basin area of the Moon and along possible traverses for the Endurance mission. Bella started in the group as a summer intern with Endurance-P, a strategic partnership between Purdue and NASA's Jet Propulsion Laboratory, and continued research on the topic into the academic year.

Garrett Kirby, Undergraduate Researcher

Garrett Kirby is an undergraduate archaeology major at the University of Evansville, Indiana. He is interested in archaeobotany, maritime archaeology, and non-destructive archaeology. His passion for archaeology has taken him across the world: he helped excavate an ancient Roman fortress beside the Black Sea, assisted in the discovery of a medieval manor in England, and discovered & identified a sunken shipwreck in the Turks & Caicos, Caribbean. He is assisting the Bramson Research Group with non-destructive ground-penetrating radar work at Fort Ouiatenon, a 1700s fur-trading outpost along the Wabash River.
