Walton is African-American, originally from
Detroit, Michigan, and was educated in the
Detroit public schools. As a child she made a
letter frequency table from her children's dictionary, and as a high school student, seeking a way to "do logic puzzles all day and get paid for this", she was already planning a career as a mathematics professor. She graduated from
Michigan State University in 2005, and completed her PhD at the
University of Michigan in 2011. Her dissertation,
On Degenerations and Deformations of Sklyanin Algebras, was jointly supervised by
Toby Stafford and
Karen E. Smith, and based in part on her work as a visiting student at the
University of Manchester, where Stafford had moved. Walton did postdoctoral research at the
University of Washington and the
Mathematical Sciences Research Institute, and became a
C. L. E. Moore instructor at the
Massachusetts Institute of Technology from 2012 to 2015. She came to
Temple University as Selma Lee Bloch Brown Assistant Professor of Mathematics in 2015 . She moved to the
University of Illinois in 2018. She joined the faculty at
Rice University in 2020. ==Recognition==
