Dr Udry’s research focus is planetary igneous petrology, including martian petrology. She is particularly interested in understanding martian magmatic processes using meteorites and surface rock compositions. Dr. Udry’s research program seeks to better constrain the interior composition, magmatic processes, and general evolution of the planet Mars through meteorite and rover data analyses. These martian studies include comprehensive petrological analyses of martian samples to mimic the scale of terrestrial geological studies. Her group also analyzes martian rover data to understand the formation of rare martian rocks with felsic compositions. In addition to martian igneous rocks, Dr. Udry’s group studies the asteroidal enstatite-rich meteorites, including aubrites and enstatite chondrites, which are geochemical analogs to Mercury, to better constrain elemental partitioning at highly reduced conditions. Dr. Udry uses a variety of classic petrological tools such as microscopy as well as electron and ion microprobe analyses, Laser Ablation ICP-MS, and thermodynamical modeling.
