Dr. Foster's scholarship encompasses a range of topics related to political communications, digital culture, and media literacy, focusing on memes. Her work includes a national study of impactful media literacy practices, examining disinformation through the "hacking" of digital cultures and the use of cultural heritage rhetoric in memes. Her dissertation, The Social Base of Memes: Expressions of Identity, values, and aesthetics in Queer digital folklore, connected the folkloric retelling of the Stonewall Riots to the functions of memes in digital cultures to create social spaces for discourses on identity and values. In the summer, she serves as the curriculum lead for the Salzburg Academy on Media and Global Change, an international study abroad program that brings students together through transformative media pedagogies.
