Research interests:

Dr Udry’s research focus is martian and terrestrial igneous petrology. She is particularly interested in understanding martian magmatic processes using meteorites and surface rock compositions. Her projects include investigation of ancient martian magmatic water degassing using in situ light lithophile elements and isotope analyses, thermodynamical modeling of magmatic evolution, and petrology of martian meteorites. Dr Udry uses a variety of classic petrological tools such as microscopy as well as electron and ion microprobe analyses.
