Julie Castillo is a planetary scientist, specialiaing in Solar system ices and icy objects. She is involved in both laboratory work and numerical modeling of relevance to Jupiter's and Saturn's satellites in order to support the interpretation of observations from the Galileo and Cassini missions and the preparation of future missions to the outer Solar system.
