Valerie Payré

Assistant Professor

Dr. Valerie Payré is an Assistant Professor in the School of Earth, Environment, and Sustainability (SEES). She is a planetary geologist, the instructor of SEES 2410: Mineralogy and SEES 3608: Planetary geology, and the outreach and event officer in SEES.

Dr. Payré is a planetary geologist and Co-I on the SuperCam instrument as part of the Mars 2020 rover team (https://science.nasa.gov/mission/mars-2020-perseverance/). Her primary research interest is understanding the evolution of planetary bodies, especially Mars and Venus, to better constrain the Earth's geological past. Her work aims to assess the surface and interior evolution of Mars and Venus, crossing several disciplines that are usually not intimately linked, such as igneous petrology and sedimentology. Dr. Payré and her group use a wide breadth of techniques including observational rover and orbital data, modeling, and experimental petrology.
