Research Interests
- biting flies
- insects associated with carrion
- insect diversity in northern Ontario
- insect trap technology
My research areas are: the role of dispersal in insect and mite populations, stable flies as pests of dairy and beef farms, and insect diversity in the Hudson bay lowlands. I also study insects that colonize corpses, such as blow flies and carrion beetles.
Teaching

BIOL 1020H: Foundations of Biodiversity
Information for prospective students:
My students usually work with insects in the field, often with a lab component looking at behaviour. Typical studies include population monitoring, experiments with density effects on dispersal, flight mill studies, insect succession on carrion, sampling forensically important insects over carcasses. Other projects have included population studies based on sampling other taxa.
