I am interested in the ecology and evolution of host-parasite interactions. I completed my B.Sc. (Zoology) at Brandon University, Manitoba (1985) and my Ph.D. at the University of Exeter, England (1990). Prior to my appointment at the University of Lethbridge in 1996, I completed Post-doctoral fellowships at the University of Zurich in Switzerland (1993) and at the University of Alberta (1996). My research roots lie in understanding the complex communities of gut parasites that are characteristic of freshwater and marine waterfowl. During my post-doc years, I shifted emphasis to empirical tests of parasite-induced effects on host and parasite performance, using amphibian and fish model systems. My current focus combines empirical approaches in the lab and field, with field-based monitoring and molecular and earth-science tools, to test hypotheses regarding the nature of the complex interactions that occur between hosts and their parasites.
