Narrative of Research Experience
Major area of interest is planetary surface processes, with a focus on wind, fluid, and volcanological
modification and rates. Methodologies include field, remote sensing, laboratory, and theoretical
investigations. Bridges is a Co-investigator on the Mars Reconnaissance Orbiter (HiRISE) and Mars
Science Laboratory (ChemCam, and is and has been a PI and Co-I on many NASA research grants.
