Scientific Interests: Briony's thesis research was on the composition, morphology, and transport history of sedimentary deposits in the north polar region of Mars. Her current interests include using spectroscopy and terrestrial analogs to constrain the habitability of paleoenvironments on Mars, explosive volcanism on Mars and the Moon, and sand sources and transport dynamics on Mars. To investigate these topics, Briony primarily uses near-infrared (OMEGA/CRISM/M3) and thermal-infrared (TES/THEMIS) spectra of planetary surfaces and laboratory samples.
