My research focuses on understanding how people interact with information in onliny systems. Broadly, the topics I have researched include recommender systems, information systems, user modelling and personalization. Specific focuses have been on

  • Evaluation: what it is that people expect from intelligent systems
  • Reproducibility: how can we recreate the results that others have attained
  • Context: how relevance changes depending on the situation in which a person uses the system
  • Health: how can intelligent information systems be used to help people lead healthier lives
