Research Spotlight

Stacy, Emerald. "Undermining the “Bad at Math” Identity: Overhauling Differential Calculus to Empower Marginalized Students." MAA Notes Volume on Diverse Equitable and Inclusive Issues in Calculus Programs (2021)

Stacy, Emerald. "Totally p-adic Numbers of Degree 3." Proceedings from Algorithmic Number Theory Symposium XIV (2020).

Petsche, Clayton, and Emerald Stacy. “A dynamical construction of small totally p-adic algebraic numbers.” Journal of Number Theory 202 (2019): 27-36.

In Gendered Voices, Feminist Visions: Classic and Contemporary Readings, a piece I wrote called “Math Camp for Girls” in included.  This textbook was published in July 2019 by Oxford University Press.


My research area is in Algebraic Number Theory.  More specifically, I study totally p-adic numbers of small height.

In addition, I work to make mathematics more inclusive as a discipline by speaking at conferences on the scholarship of pedagogy.
