In 1998, McKellar earned a Bachelor of Science degree in mathematics (summa cum laude) from University of California, Los Angeles , where she was a member of the Alpha Delta Pi sorority. As an undergraduate, she coauthored a scientific paper with Professor Lincoln Chayes and fellow student Brandy Winn titled "Percolation and Gibbs states multiplicity for ferromagnetic Ashkin–Teller models on ." Their results are termed the "Chayes–McKellar–Winn theorem". Later, when Chayes was asked to comment about the mathematical abilities of his student coauthors, he told The New York Times, "I thought that the two were really, really first-rate." As a result of her past collaborative work on research papers, McKellar is assigned the Erdős number four, and the Erdős–Bacon number six.
