 ​Aggregation in parasites:
​theory and tests

Arrenurus water mites infecting a Lestes disjunctus damselfly.
Aggregation of parasites is a general law in parasitiology: we are addressing why parasites might be aggregated, through use of statistical models.

​Impacts of parasites on Arctic breeding birds

Northern common eider duck die-off on Mitivik Island, Nunavut.
Through a series of collaborations, we are addressing impacts of avian cholera and gut helminths (and contaminants) on Arctic-breeding Eider ducks. 

​Host species range for parasites

Engorged mite (left panel) and a resisted mite (right panel) of same species. Hosts: Nehallenia spp.
Some parasite species exploit few host species, whereas others have broad host ranges. We explore determinants and consequences of  host species ranges.
Other current and past research from the lab: theses

These are several recent theses from my lab. Some students have been co-supervised.
