Trevor is a Planetary Geologist with Jacobs Technology Engineering and Science Contract Group (ESCG) at NASA's Johnson Space Center in Houston, TX. In his current position he manages the Spectroscopy and Magnetics Laboratory conducting detailed spectroscopic analysis on a wide range of astromaterials and planetary analogue materials. This research provides physical, chemical, and mineralogical information used to interpret data from various planetary landers, rovers, and orbiting spacecraft. Prior to his work at JSC, Trevor was a Payload Uplink Lead for the Miniature Thermal Emission Spectrometer (mini-TES) aboard NASA's Mars Exploration Rover (MER) mission.
Trevor is also currently involved in numerous analog field studies including the International Hawaii Analog Field Test and Desert Research and Technology Studies (Desert-RATS). This work supports NASA's analog mission activities intended to integrate interdisciplinary field experiments in preparation for future human and robotic missions to asteroids, the Moon, and/or Mars.
