Kathy's research covers a broad range of topics including the origin and evolution of volatiles throughout the solar system and the role of dynamics, chemistry and atmospheric evolution in understanding this. She has spent more than a decade working on planetary missions including ground calibration, operations planning, data analysis and inflight calibration. Kathy was a science team member on the Cassini Ion Neutral Mass Spectrometer (INMS; 2007-2012), and Rosetta Ion Electron Spectrometer (IES; 2012-2018) teams. She served as the Rosetta IES Liaison to the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) mass spectrometer team. She is a Co-I on the Volatile Investigation Polar Exploration Rover (VIPER; 2022-present), a science team member of the Europa Clipper Plasma Instrument for Magnetic Sounding (PIMS; 2018-present) and a Co-I on the Lunar Reconnaissance Orbiter (LRO) Lyman-alpha Mapping Project (LAMP; 2013-present). She served as the Volatiles Theme Lead for LRO, served on the 2016 Ice Giants Science Definition Team, was the Project Scientist for LAMP, and for the Io Volcano Observer (IVO) Phase A study.
