Ernest Pujol Leon earned his PhD from the Program in Literature at Duke University in 2025, with a dissertation titled “Karl Marx, Philosopher of Technics: Critique, Alienation, and the Materiality of Social Power.” He previously completed his Master's degree in the same program in May 2022. As a graduate student, he served as a Bass Digital Education Fellow during the 2022–2023 cohort, where he contributed to a collaborative project between the Computational Thinking initiative and Duke Learning Innovation. This effort produced a self-paced online course introducing the programming language R and fundamental principles of data science, accessible to undergraduate students and the wider Duke University community. Additionally, he received a Bass Instructional Fellowship in 2022–2023 and was listed among fellowship recipients for 2023–2024.

Pujol Leon instructed LIT317S Media Theory in Fall 2024 for the Program in Literature, a course fulfilling a major requirement for the Film/Media track. It examined the material and technical infrastructure shaping knowledge production and dissemination, alongside the cultural impacts of technical media from writing to the internet. The curriculum integrated historical and theoretical analysis with practical experimentation using technologies such as the codex book, phonography, sound registration, photography, cinematography, video, virtual reality, digital computation, and the internet. His scholarly work includes the publication “Benjamin's Phantasmagorias: Socially Necessary Semblance and the Commodity Form” in South Atlantic Quarterly (2025), a book review of Adorno and Marx: Negative Dialectics and the Critique of Political Economy for Marx & Philosophy Review of Books (2022), and presentations such as “Digitality and Control before the Information Age: Charles Babbage, Andrew Ure, and the 'General Intellect' of the Factory” at Brown University. He also participated in a roundtable on Generative AI in writing centers at the Fall 2024 Ivy Plus Writing Consortium Conference, served as Graduate Student Liaison for the Program in Literature in 2021–2022, and is a member of an editorial collective.
