My lab studies lung disease in horses, cats, and dogs. We look for relationships between air pollution and the incidence of asthma. As well, we are developing more detailed ways of understanding how lung diseases arise, and finding more accurate methods for diagnosing them.

Graduate students joining my team at Guelph get unrivalled opportunities to work in the lab and field answering research questions at the cutting edge of science with direct environmental and societal relevance. This important research is exciting, challenging and rewarding for the student, for me as the supervisor and for everyone else in the team.

My research interests include bullying and cyberbullying, policing, and victimization. I am particularly interested in the ways in which the peer, family, and school contexts influence adolescents' involvement in cyberbullying, and how groups of adults collaborate to prevent and respond to cyberbullying.
