William L. Hamilton

I am an Assistant Professor of Computer Science at McGill University and a Canada CIFAR AI Chair at the Mila AI Institute of Quebec. I develop machine learning models that can reason about our complex, interconnected world.

Broadly, my research interests lie at the intersection of machine learning, network science, and natural language processing, with a current emphasis on the fast-growing subjects of graph representation learning and graph neural networks.

Recent news
  • March 2020 Excited to announce the next Graph Representation Learning Workshop will take place at ICML 2020! Details to follow in the coming weeks, as the workshop may be virtual-only given the evolving COVID-19 pandemic.
  • January 2020 Invited talk at the AAAI Deep Learning on Graphs Workshop. I discussed my lab's recent work on "Meta Learning and Logical Induction on Graphs." Check out the slides at here.
  • December 2019 The Graph Representation Learning Workshop at NeurIPS 2019 was a huge success, with over a thousand attendees!
  • November 2019 Our new CLUTRR dataset for evaluating natural language reasoning was presented at EMNLP 2019!
