Jackie Chi Kit Cheung is an Associate Professor at the School of Computer Science, McGill University, and holds the Canada CIFAR AI Chair at Mila - Quebec AI Institute. His research bridges Natural Language Processing (NLP) with insights from linguistics and psychology, focusing on system evaluation, automatic summarization, and computational semantics.

• Key Affiliations: Mila - Quebec AI Institute, Centre for Research on Brain, Language and Music, Centre for Intelligent Machines

His lab develops state-of-the-art NLP systems while proposing challenge datasets and evaluation measures. Research emphasizes broader applications in education, health, and language revitalization. Recent work includes the ACL 2024 COSMIC framework for summarization evaluation (SAC Award).

He teaches advanced courses like Formal and Neural Models of Pragmatics (Winter 2024) and Evaluation of NLP Systems (Winter 2025). His group includes 10 PhD students, 8 Master's students, and active collaborations with institutions like Mila and SRI International.

• Scientific Recognition:
  • Canada CIFAR AI Chair
  • SAC Award for ACL 2024 paper

Current projects explore representational harms in LLMs, long-context modeling, and mechanistic hallucination mitigation. Students and co-supervised researchers work on fairness, robustness, and commonsense reasoning.
