After completing my B.Sc., I worked with Charles Colbourn, studying uniformly sparse graphs. I then investigated aspects of nonmonotonic reasoning with David Poole and Romas Aleliunas, in a then-new area known as 'uncertainty in AI', including the subarea of causality.
I have also always had an interest in computer graphics, and pursued several visualization projects.
During the heydey of the iPhone and iPad, I became interested in mobile computing, and was able to combine all three interests in a piece of software called iCausalBayes

The rat prostate and human embryo reconstructions on this page were painstakingly constructed with Winsurf, my rewrite of a program called SurfDriver, written by Scott Lozanoff and David Moody.
The embryo visualizations are part of a project called DREM (google it) and the prostate was part of a long standing research program led by Barry Timms, now retired.
The brain visualization was part of a related project.
WinSurf, and its predecessor, have been used world-wide.
Robert Spence, author of a respected text on Information Visualization noticed this work and included it in the third edition of his text. A career highlight.
This work has an interesting pedigree. The causal graph of the guinea pigs comes from a paper by Sewell Wright written in 1920. Agent Charles Eppes explains on episode 3 of Numb3rs how to fight bioterrorism using "advanced statistical analysis and graph theory". One of the first uses of Bayes nets in TV crime fighting.
The successful creation of this app was the result of perfect timing: terrific teamwork within the Department of Computer Science, the iPhone launching just when Chad Jones, a former Apple employee happened to be teaching sessionally at the University of Saskatchewan, and complete and utter ignorance of formal university processes.
We just did it! The app appeared on CBC behind Peter Mansbridge, in MacLean's magazine, and was used by the institution to promote itself as a haven for "teamwork and ingenuity" in national advertising.
