Note: I am currently on leave from McGill and Mila and am not taking new PhD or MSc students. For other opportunities in the McGill NLP Group, see the page below.

Potential Topics

These are some topics that interest me. But I am open to new ideas and topics. In fact, a major portion of your research time will be spent on finding good problems to work on.

  1. Representation Learning and Computational Linguistics — text embeddings, interpretability, multilingual representations
  2. Reinforcement Learning for LLM Reasoning — reward design, process supervision, search
  3. Safety and Alignment — scalable oversight, tiered alignment, agent safety
  4. Language Agents — web navigation, tool use, retrieval-augmented generation, hallucination mitigation
  5. Multimodal Understanding — language and perception, vision-language reasoning, world models
  6. New Architectures and Training Objectives — mixture of experts, positional embeddings, pre-training and fine-tuning objectives

Some of these topics can be co-supervised with other faculty at MILA and McGill.
