Dr. Matthew Chojnacki

Dr. Matthew Chojnacki is a Senior Scientist working with the High Resolution Imaging Science Experiment (HiRISE) mission at the Planetary Science Institute (PSI). He is a planetary geologist who has been involved with the scientific exploration of Mars for over a decade. His recent research has focused on the geologic, morphologic, and climatic evolutions of Mars, particularly: aeolian transport and sand dune dynamics, the thermophysical and spectral properties of the martian surface, aqueous alteration and weathering of planetary crusts, and terrestrial analog studies.

As a HiRISE Co-Investigator, Matt co-manages the HiRISE Operations Center (HiROC) photogrammetry lab, and participates in HiRISE-related targeting and initial science assessments. Most recently he participated on the Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) mission by leading the stereo photogrammetry Digital Terrain Model (DTM) production.
