Xavier Bach

Xavier Bach is a Lecturer in Language Sciences at Toulouse Jean Jaurès University, affiliated with the Cognition, Languages, Ergonomics (CLLE) research unit. His academic career spans prestigious institutions including Trinity College, University of Oxford, where he served as a Junior Research Fellow (2019-2023) and Lecturer in French Linguistics at Christ Church College (2021-2023), followed by an ATER position at Toulouse Jean Jaurès University (2023-2024) before securing his current permanent lectureship.

His research focuses on core areas of linguistic theory with particular emphasis on Inflectional Morphology, Syntax, and Diachronic Linguistics. Key thematic strands include:

• Romance language typology and variation (especially Occitan, Oïl dialects, and Italian)
• Austronesian language documentation
• Cartographic representation of linguistic variation
• Language contact phenomena
• Gender-inclusive language innovations

Analysis of his recent publications reveals a consistent trajectory in morphosyntactic research, with significant contributions to understanding inflectional systems in Romance languages, particularly Occitan. His work bridges historical linguistics and contemporary sociolinguistic developments, notably examining how language contact shapes grammatical change (as in negation systems) while simultaneously documenting modern linguistic innovations like non-binary language forms. This dual focus on historical depth and contemporary relevance characterizes his scholarly approach.

Bach actively contributes to major collaborative research initiatives including the ParCoLab Parallel Corpus project for regional French languages. His teaching portfolio at Toulouse Jean Jaurès University covers foundational and advanced topics in morphology and phonology, reflecting his research expertise in linguistic structure and variation.

As a core member of the CLLE research unit, Bach participates in interdisciplinary work spanning descriptive linguistics, language documentation, and cognitive approaches to language structure. His research integrates theoretical frameworks with empirical data from both historical texts and contemporary language use, contributing to broader understanding of linguistic diversity and change in Romance language contexts.
