Applications are invited for a postdoctoral position in planetary astronomy within Caltech’s Division of Geological and Planetary Sciences. The successful applicant will collaborate with the de Kleer research group on the interpretation of thermal data of icy moons and small bodies from ALMA, the VLA, and JWST. The work will involve reduction and analysis of thermal data, as well as collaboration on the development of (sub)surface models which will be used to characterize (sub)surface processes on these worlds. The project requires training in mathematics and physics as well as strong scientific programming skills. Experience working with astronomical or spacecraft data is required, and experience with radio interferometry and/or mid-infrared spectroscopy is preferred. The successful candidate will have opportunities to mentor graduate and undergraduate students. The start date is flexible, but will be no sooner than June 1, 2022. The initial duration of the position is one year, with renewal for up to two additional years. The position offers a competitive salary, benefits, and annual research budget, as well as access to Caltech’s extensive resources, including the Keck and Palomar Observatories and computational facilities. Applications are due May 20, 2022.
