After receiving her Bachelor of Science in astronomy and physics from the University of Washington and Master of Arts in Earth and environmental sciences from Wesleyan University, Tanya took a break from academia. She spent 4 years working in mission operations as an assistant staff scientist at Malin Space Science Systems on the Mars Reconnaissance Orbiter Context Camera (CTX) and Mars Color Imager (MARCI), as well as the Mast Cameras (Mastcam), Mars Hand Lens Imager (MAHLI), and Mars Descent Imager (MARDI) aboard the Curiosity rover. She was also involved in public outreach activities for those missions, as well as with The Mars Society and The National Space Society. For many years she was also the head of space and/or science track programming for Norwescon, the Pacific Northwest's largest sci-fi and fantasy convention, only relenquishing the position because she moved to the other side of the continent. She now dually resides in Toronto, Ontario and Tempe, Arizona.
