**Research interests**

Sarah is interested in the teaching and learning of undergraduate mathematics. In particular, her work is focused on student understanding of ideas in geometry. For her thesis, she is examining how students think about and solve problems involving transformations which include translations, reflections, rotations, and dilations, better known as shifts, flips, turns, and stretches.
