My research sits at the intersection of colonial Latin American history, art history, archaeology, and digital humanities. I investigate how Indigenous communities in Mexico created, maintained, and adapted knowledge systems under Spanish colonialism. This work unfolds across five interconnected thematic clusters.

Colonial Education and Learningscapes

How did Nahua ("Aztec") education survive the traumatic disruptions of the Spanish invasion? My first monograph, An Unholy Pedagogy: Visions of Learning from Mesoamerica, 1300 to 1650 (Cambridge University Press, 2026), rethinks education studies by centering Indigenous visions of learning. I track education systems before the Spanish-Catholic invasion, examining the writings, art, and architecture of Nahua communities. By analysing Nahuatl primary sources and historical art and archaeological evidence, I reveal how Nahua students transformed pedagogy, shaped learning, and preserved local knowledge in the first schools of the Americas.

Nahua Visual and Material Culture

A significant strand of my work examines how Nahua artists, scribes, and communities used visual and material culture to assert agency, preserve knowledge, and negotiate colonial power. I have published on warrior women and martial mothers in the Florentine Codex, demonstrating how Indigenous artists depicted gendered power in ways that challenge Western assumptions about Mesoamerican society. I am currently developing a book manuscript, Mesoamerica's Mothers in the Making, which redefines the dimensions of powerful Indigenous women at the crossroads of Spanish colonialism.

Games, Digital Media, and Heritage

El Nuevo Coyote, a 19th-century Mexican board game

I investigate how Mesoamerican cultures are represented in video games, board games, and digital media, interrogating the colonial affordances embedded in popular digital experiences. My article "As the Digital Teocalli Burns" examines how gamified representations of Mesoamerica displace sacred spaces and reproduce colonial narratives. I co-created the "Re-Imagining Coyote" augmented reality exhibition at the Museum of Archaeology and Anthropology in Cambridge, which traveled internationally to Tijuana and San Diego. A second monograph, Ready Conquistador 1: Digital Colonial Game vs. Mesoamerican Heritage, is in progress.

Ethnobotany and Foodways

Mesoamerican food culture was deeply intertwined with art, ritual, and knowledge systems. My research explores how amaranth and chia, two critical seed crops, functioned not merely as food but as materials for sculpture, timekeeping, and ritual practice. I examine how Nahua women served as timekeepers, "mountain killers," and dough-body crafters, shaping food into powerful cultural objects. This work contributes to broader conversations about Indigenous knowledge systems, embodied practices, and the intersection of food studies with art history and archaeology.

Manuscripts, Digital Humanities, and AI

I am leading the first comprehensive study of a sixteenth-century Nahuatl-Latin lectionary in the British and Foreign Bible Society's collection at the Cambridge University Library (BFBS MS 375). This work, conducted through the Hidden in Plain Sight Project with Queen Mary University of London, investigates "Aztec Tipp-Ex": Indigenous technologies used akin to modern liquid paper, recovering erased artwork and Mesoamerican glyphs in colonial manuscripts. In collaboration with the AI Research for Cultural Heritage Hub (ArCH) at Cambridge's ai@cam initiative, I use computer vision and machine learning to detect and analyse material interventions across a growing corpus of Indigenous-colonial texts.
