I am Professor and Chair of the Department of Mathematics at Ryerson University. My research interest is in graph theory, with applications to graph real-world complex networks, such as the web graph and on-line social networks (OSNs), and graph searching games such as Cops and Robbers. I am an adjunct professor at Dalhousie University, and I am a member of Graphs at Ryerson (G@R) and RAMLab. My research is supported by grants from NSERC, MPrime, and Ryerson. I won Ryerson Faculty SRC Awards in 2011 and 2009 for excellence in research, and the YSGS Outstanding Contribution to Graduate Education Award in 2012. I am co-Editor-in-Chief of Internet Mathematics, and I am on the Editorial Board of Contributions to Discrete Mathematics. I serve on the Board of Directors of Mprime.
Ryerson Mathematics began its Masters in Applied Mathematics in September 2009. Please contact me if you are interested in working with me as your supervisor.
