The Exploration of Planetary Ices and Climates (EPIC) group in the Laboratory for Atmospheric and Space Physics (LASP) at CU Boulder investigates the atmospheres and surfaces of icy worlds using numerical models and data from spacecraft and Earth-based observatories. We are especially interested in the thermal environments and behavior of volatiles on these bodies, including the polar regions. Our quantitative approach includes the development of numerical heat, vapor, and radiative transfer models with wide applicability to problems in planetary science. Data analysis efforts focus on multi-spectral and hyper-spectral imaging for compositional studies, thermal infrared atmospheric sounding and surface mapping, and inversion techniques.

EPIC is composed of researchers at all levels, from undergraduates to postdoctoral scholars and members of LASP’s permanent research staff. We welcome inquiries for possible opportunities from individuals representing a diverse range of backgrounds. The EPIC group is a welcoming environment, where all perspectives are respected and everyone is valued for their contributions.
