I was born and raised just outside Montreal in Québec, Canada.  My interest in cestodes of elasmobranchs dates back to my days as an undergraduate at Macdonald College of McGill University.  I pursued this interest by undertaking an MSc at the Institute of Parasitology working on the biology and taxonomy of helminth parasites of four sympatric skate species from the Bay of Fundy, New Brunswick, Canada. 

During my MSc studies, I spent much of my time at the Huntsman Marine Science Centre in beautiful St. Andrews, New Brunswick, Canada, and gained a great appreciation for marine biology.  Shortly after the completion of my MSc, I began a PhD in the Department of Biology at the University of New Brunswick under the supervision of Drs. Michael D. B. Burt and Gary W. Saunders, assessing host specificity and its determinants in cestodes infecting elasmobranchs from the northwest Atlantic (completed in September 2007).  Since September of 2007, I have been based at the University of Otago, where I am working as a postdoctoral fellow in the Parasitology lab under the supervision of Prof. Robert Poulin. I am studying the evolutionary ecology and molecular systematics of cestodes (Tetraphyllidea) infecting elasmobranchs, with emphasis onthose infecting rajid skates.  Additionally, I am using molecular tools to determine the ecological roles played by squid, teleosts and marine mammals in the transmission of marine tapeworms. My work is based primarily at the University of Otago in collaboration with the Falkland Islands Fisheries Department.  For a more complete description of the projects, please visit our website under the heading “Molecular systematics and coevolution of tetraphyllidean cestodes and rajid skates” or contact me directly.
