Professional Biography

Andrew is broadly interested in the applications of computer vision and machine learning to the study of planetary surface remote sensing and geomorphology. At SETI he is an instrument scientist for the NASA VIPER VIS camera instrument and a collaborator on the Mastcam-Z instrument aboard the Perseverance Mars rover.

He also maintains the popular open-source SpiceyPy software library.
