Andrew Hedding is a syntactician and linguistic fieldworker. His theoretical research focuses on how questions are formed and the ways that discourse influences word order. He primarily investigates Mixtec, an Indigenous language of Mexico, conducting fieldwork with speaker communities in Mexico and California since 2017. He teaches courses ranging from introductory linguistics to advanced undergraduate and graduate syntax, as well as specialized courses on the relationship between syntax and semantics.

Hedding is a recipient of the 2026 Digital Humanities Summer Fellowship for the project, "A Public Digital Archive of San Martín Peras Mixtec." This project will transform an existing fieldwork database into a publicly accessible digital dictionary of San Martín Peras Mixtec, which will advance community-centered digital humanities and model sustainable approaches to Indigenous language archiving. The dictionary platform will integrate audio recordings, linguistic annotation, and searchable lexical data to support language learning, community access, and scholarly research.
