William Kennedy

Member of Technical Staff


I joined Bell Labs as a postdoctoral member of technical staff in the Mathematics of Networks and Communications Research Department at Bell Laboratories, Alcatel-Lucent, Murray Hill, NJ. At the time my research was partially funded by an NSERC Postdoctoral Fellowship.  In 2013, I was converted to a member of technical staff.




I received a Ph.D. from the Department of Mathematics and Statistics and the School of Computer Science at McGill University, Montreal, Quebec in 2011. My supervisors were Bruce Reed and Bruce Shepherd. My research was partially funded by an NSERC Canadian Graduate Scholarship.

Ph.D. Thesis: Fractional Edge and Total Colouring

I received a M.Sc. from the Department of Computing Science at the University of Alberta, Edmonton, Alberta in 2005. My supervisors were Ryan Hayward and Guohui Lin. My research was partially funded by an NSERC Canadian Graduate Scholarship.

M.Sc. Thesis: Strictly Chordal Graphs and Phylogenetic Roots

I received a B.Sc. in Mathematics, specialization Computational Science, at the University of Alberta, Edmonton, Alberta in 2003. My summer research under Ryan Hayward was partially funded by an NSERC Undergraduate Student Research Award.
