The Owner and your local Computer Science prof at PageWizard Games, Learning & Entertainment, in Sunnyside, Manitoba (RM of Springfield).
Recently, I have been interested in scheduling theory and its ties with graph theory in the development of approximation algorithms and computational complexity results. Widely I have interests in algorithmic problems of Theoretical Computer Science and Combinatorial Optimization, with a specific focus at the crossroads of approximation algorithms, scheduling problems, and parameterized complexity. At the present time I am investigating parallel machine scheduling problems and hard scheduling/packing problems on graphs, in an attempt to further unravel their underlying complexities. Many of the algorithmic problems I investigate have applications in Operations Research.
With many years of experience teaching, I have held positions, such as Assistant Professor, Lecturer, Instructor, and Researcher for public universities such as The University of Manitoba, The University of Western Ontario, St. Francis Xavier University, and The University of Regina, and my educator experience also includes, but is not limited to, having worked for respected educational institutions such as The Royal Aviation Museum of Western Canada and Mad Science of Manitoba.Degrees
