Brief biography

My current research interests include the taxonomy and community ecology of parasitic helminths and ectoparasites of various vertebrate hosts including the behavioural, biogeographical, evolutionary, life cycle and developmental aspects of parasites, and their intermediate and definitive hosts. The major groups currently being studied include shorebirds, bats and shrews.

Shorebirds: studies on shorebirds have focused on helminth communities in a variety of species as well as an analysis of the accumulation of methyl mercury in the tissues of migrant semipalmated sandpipers that feed on the contaminated amphipod Corophium volutator.

Bats: using specimens held by the New Brunswick museum, several native species of bats are being surveyed for seasonal changes in parasite loads and diversity.

Shrews: currently looking at the parasite communities of the masked (common) shrew, Sorex cinereus, in the Grand Lake Meadows region of New Brunswick.
