REMOTE SENSING

Scientific exploration of the solar system is driven by trying to understand fundamental questions regarding how Earth and our solar system formed and evolved over time.  In my research, I combine laboratory measurements (see below) with remote sensing observations across visible, near- and thermal-infrared wavelengths to address fundamental questions on the formation and evolution of airless bodies like the Moon, Mercury, asteroids and planetary satellites (e.g. Phobos and Deimos).

LABORATORY SPECTROSCOPY

While remote sensing observations provide key insights into the composition and evolution of planetary surfaces, an important component to interpreting those remote measurements is a suite of laboratory measurements of well-characterized analogue amterials under the appropriate temperature and pressure conditions.  Using environment chambers at the University of Oxford and Brown University, I have measured the thermal emission of pure minerals, mixtures of pure minerals, lunar soils and meteorites under a range of environmental conditions including Earth-like, lunar-like and asteroid-like conditions.  These laboratory measurements are key for interpreting current and future thermal infrared observations of planetary surfaces and in better understanding the thermal gradients found in the upper 100's of microns in planetary regoliths.
