She completed a bachelor's degree from Berkeley in astrophysics in 2007, with a minor in physics. She did her graduate studies at Harvard University, completing a doctorate in astronomy and astrophysics in 2012 under the supervision of David Charbonneau.

The transit-timing variation method (TTV) is one of two techniques, along with the transit-duration variation method, proposed in 2001 by astronomer Jordi Miralda-Escudé. TTV was amplified upon in 2004 by astronomers Matthew J. Holman and Norman W. Murray; and by Eric Agol [de] , Jason Steffen, Re’em Sari, and Will Clarkson. Ballard was the principal investigator in the 2009 application to use the Spitzer Space Telescope to examine "The First Exoplanet Smaller than the Earth". Ballard led the team which precisely estimated the diameter of Kepler-93b to within 1 percent, using TTV.

Sarah Ballard (born 1984) is an American Professor of Astronomy currently at the University of Florida. She has been a Torres Fellow at the Massachusetts Institute of Technology, a L'Oreal Fellow, and a NASA Carl Sagan Fellow.
