Heather Lent

Assistant Professor

In my work on Creole and other lower-resourced languages, I take community needs—not simply inherited English benchmarks—as a starting point. Across my research, I study machine translation, transfer, multilingual data quality, language-model security, and the ethics of security research.

Heather’s research asks how language technology can serve languages and communities overlooked by mainstream NLP. She develops methods, datasets, benchmarks, and machine-translation systems for Creole and other lower-resourced languages, combining work on transfer, sociolinguistic variation, semantic parsing, and data quality with direct attention to what communities actually need.

She has also established a complementary strand in multilingual language-model security and research ethics. This work examines multilingual vulnerabilities and defences, alongside broader questions of harm minimisation and responsible disclosure. Across both strands, community considerations are part of the technical design—not an assessment added after a system is built.

Creole and lower-resourced NLP

Language modelling, transfer, machine translation, semantic parsing, and evaluation beyond the best-resourced languages.

Community-grounded evaluation

Letting community priorities and sociolinguistic realities change the tasks, datasets, benchmarks, and measures of success.

Multilingual security and ethics

Testing whether vulnerabilities, defences, and disclosure practices protect lower-resourced languages on their own terms.

How Good is Your Wikipedia? Auditing Data Quality for Low-resource and Multilingual NLP

Kushal Tatariya, Artur Kulmizev, Wessel Poelman, Esther Ploeger, Marcel Bollmann, Johannes Bjerva, Jiaming Luo, Heather Lent, and Miryam de Lhoneux

Audits all non-English Wikipedia editions and shows why data quality—not language coverage alone—must be a first-class concern in multilingual NLP.

Questions worth working on

I am interested in projects on lower-resourced and multilingual NLP, Creole languages, machine translation, data and evaluation quality, multilingual security, and responsible research practice.
