Applicant -- Theoretical and Experimental Studies of Icy Regolith Climate Systems on Planets and Satellites

Wednesday, August 29, 2018

I will present an overview of my 20 years of research on ice-bearing planets and satellites. My research concerns the microphysics of icy regolith systems and their interactions with climate on both local and global scales.  The regolith, atmosphere (or exosphere), and volatiles form a coupled system that evolves through time, driven by changes in external forcing (insolation, orbit, obliquity, etc.). My work focuses on understanding the microphysical properties and processes that govern the internal response and feedback mechanisms.  Topics discussed will include: polar ice, frost, and ground ice on Mars, Mercury, Ceres, and the Moon; surface evolution, geomorphology and exospheres on icy satellites; regolith thermophysics; and implications for astrobiology.
