Provinces and territories of Canada

The spread of pests and pathogens, including exotic insects arriving in packing material and naturalized pests such as the Colorado potato beetle, have a substantial impact on Canadian industry and the economy. Working with food producers, provincial and federal government agencies and wildlife organizations, this project team is developing essential mathematical tools necessary for the management of our natural and agricultural resources. This past year, the group has developed a theory of spreading speeds applicable to many mathematical models of spatial spread in biological systems.

The development of the Internet and the World Wide Web has changed the way in which we gather information. No longer is information only available as in a library, with items catalogued in an orderly manner. More and more often, information is presented as it is in the World Wide Web: as a mass of items with interconnecting links. This research team aims to extract information from such web-like collections by considering both the content of the items and the link structure that connects them, and the interaction of both components.
