Tanya holds a Ph.D. in Geology with a Specialization in Planetary Science and Exploration from the University of Western Ontario. There, her research focused on the formation and evolution of features on Mars called gullies, and what they can tell us about the recent climate history of the Red Planet. She also holds a Masters in Earth and Environmental Sciences from Wesleyan University where she studied spectroscopy of hydrated minerals on Mars, and a B.Sc. in Astronomy and Physics from the University of Washington where she studied the metallicity of star clusters and recurring novae systems. Her honours include two NASA Group Achievement Awards, the Amelia Earhart Fellowship for women in aerospace and the Vanier Canada Graduate Scholarship, Canada’s most prestigious doctoral award.
