Dr. Evans received her BA from Wellesley College and her M.Sc. and PhD. from the University of Toronto, Canada.
Her major area of expertise has been in the exploration of the classical Cepheid population of our galaxy, particularly their fundamental properties (masses) and binary properties as related to star formation. For this she has made observations with the IUE, HST, Chandra, Spitzer, FUSE, WIRE, MOST, and XMM satellites. She was a major contributor to the construction of the Galactic Cepheid Database. Most recently she has been a staff scientist at the Chandra X-ray Center , where she worked in user support and ran the Einstein (Chandra) Post-Doctoral Fellowship Program . She joined SAO in 1995 and retired in 2010 to become a Smithsonian Associate. Her current research uses multiwavelength studies to determine the binary properties of fairly massive stars (Cepheids) and what they tell us about star formation and the exotic futures of these stars. Over her career she has taught at Erindale College of the University of Toronto, been a resident Astronomer at the IUE satellite and was associate director of the Space Astrophysics Laboratory at the Institute for Space and Terrestrial Sciences, York University .
Dr. Evans is a Member of the American Astronomical Society and the Canadian Astronomical Society. She also belongs to Sigma Xi and the Association of Women in Science. She has published over 90 refereed journal articles that have appeared in such journals as Astronomy and Astrophysics, Astronomical Journal, and the Astrophysical Journal.
