Humboldt State University, graduating summa cum laude in 1998.^[1] She became a doctoral student of Danny C. Sorensen in computational and applied mathematics at Rice University, where she completed her Ph.D. in 2006. Her dissertation was Fixed-Polynomial Approximate Spectral Transformations for Preconditioning the Eigenvalue Problem.^[1][2] She began working at Sandia in 2003, while she was still at Rice, and remained there after completing her doctorate.^[1]
