Welcome to my web based curriculum vitae.


I am currently a sessional instructor at the University of Manitoba, teaching in the Department of Biological Sciences. 


I completed my PhD in 2018 at the University of Otago, in Dunedin, New Zealand, with the Evolutionary and Ecological Parasitology Research Group. My research was focused on parasite-mediated interspecific interactions in a community of crustaceans. I was examining relationships between amphipods, isopods, and their parasites within freshwater communities.


I completed my master's degree at the University of Manitoba, with Dr. Jim Roth. I studied the relationships between the diet of canids, including wolves, arctic and red foxes, and their parasite communities. I also considered how other factors, including behaviour, life history, and intraspecific variation (e.g., age and sex), may also influence canid parasite intensity, abundance, and prevalence. I am interested in studying the ecology of parasites and their hosts, including the influence of parasites on trophic interactions, food webs, and behaviour. I am further interested in the impacts of parasites on predator-prey relationships and their combined effect with other stressors on their hosts.


Prior to my master's work, I completed my B.Sc. (hons) in zoology at the University of Manitoba. My honours research, with Dr. B. Hann, examined how zooplankton could be used in rapid bioassessment of lakes as they are a keystone lentic community. They occupy an intermediate trophic position in the food web of a lake and are responsive to both top-down and bottom-up trophic interactions.
