About:

Briony Horgan is an Assistant Professor of planetary science. She uses data from NASA’s satellites and rovers to understand the geologic history of the Moon and Mars, supported by lab and field work at analog sites back on Earth. Her expertise is identifying minerals using visible and infrared spectroscopy, and using those minerals to investigate planetary surface processes, and to identify habitable ancient environments on Mars. Prof. Horgan is a Co-I on the Mastcam-Z camera system for NASA’s Mars2020 rover mission.
