After working in the computer and aerospace industries, she returned to graduate study at the University of Virginia in 1997, and earned a Ph.D. there in 2007. Her dissertation, Knowing Our Neighbors: Fundamental Properties of Nearby Stars, was directed by Philip A. Ianna.
While completing her doctorate, Bartlett was a visiting assistant professor at Hampden–Sydney College in Virginia. She began working for the United States Naval Observatory in 2007, and in 2010 became Chief of the Software Products Division in the Astronomical Applications Department. She moved to the United States Naval Academy as Kinnear Chair of Physics in 2021.
