Pourang P. Irani (Ph.D.)

I am an associate professor in the Department of Computer Science at the University of Manitoba. I teach and investigate research topics in Human-Computer Interaction (HCI) in the HCI lab. I work on a variety of fields in HCI, with a concentration in the following areas:

  • Information Visualization
  • Interaction Techniques
  • Animated Displays
  • Document Navigation
  • Interfaces for Ubiquitous Devices
  • Input Devices
  • Gaming Applications
  • Computer Supported Cooperative Work (CSCW)

I am currently seeking graduate students (PhD, MSc) to work in the Human-Computer Interaction Lab. If you are interested please email me.

Nicknamed the slurpee capital of the world (for the twelfth time last year), it really is never too cold to have a slurpee in Winnipeg. Despite the freezing temperatures, life in Winnipeg is vibrant and pleasant. It is home to 700,000 people who make Winnipeg a truly multi-cultural city. Some of the cultural organizations of the city are Manitoba Opera, the Royal Winnipeg Ballet, Winnipeg Symphony Orchestra, Manitoba Museum, and Le Cercle Moliêre. Some of the city's popular festivals are the Festival du Voyageur, the Winnipeg Jazz Festival, the Winnipeg Fringe Theatre Festival, and Folklorama. Professional sports organizations based in the city include the Winnipeg Blue Bombers, the Winnipeg Jets, and the Winnipeg Goldeyes.
