Dr. Hanna Sizemore
Senior Scientist
Research Interests
Dr. Hanna Sizemore's research focuses on understanding the history and mobility of ice in regoliths. She studies ground ice on Mars, through numerical simulations of ice stability, numerical simulations of thin film migration, and through laboratory investigations of ices and Mars-analog soils. She also studies periglacial geomorphology in extraterrestrial settings. During the Mars Scout Mission Phoenix, she compared ice burial depth and morphology to theoretical predictions to better understand the climate history of the Martian high latitudes. She is currently a guest investigator on the Dawn mission to dwarf planet Ceres, involved in the global geologic mapping and analysis of periglacial features.
Professional History
Dr. Sizemore received her B.A. from Smith College in Northampton, MA with a major in physics and and a minor in math. She received her M.S. and Ph.D. in Astrophysical and Planetary Sciences from the University of Colorado, Boulder. During her first postdoc at the Laboratory for Atmospheric and Space Physics she participated in the Mars Scout Mission Phoenix. Subsequently, she was a NASA Postdoctoral Program (NPP) fellow at NASA Ames Research Center, before joining PSI in 2013.
