Elliot Sefton-Nash

Planetary Scientist

 

Main Research Fields

My research areas encompass planetary geology and remote sensing, and include questions regarding: surface properties (thermophysical, morphological, mineralogical), surface-atmosphere interaction, volatiles, habitability, computational methods and planetary GIS. I do spectroscopy and radiometry from the visible to far infrared, analysis of planetary image data, and theoretical modelling in support of observations.


Broadly, my research aim is to map and understand the composition, distribution and role of volatiles in the context of past and present solar system habitats, and targeting of sites for future human and robotic exploration. Special focus is given to the water-mediated history of Mars' surface and atmosphere, and its astrobiological implications.


Much of this work concerns Mars and the Moon, but results can have implications for asteroids, comets, and exoplanets.
