Research Focus

My research focuses on parasite epidemiology and the prevention and control of parasitic disease worldwide. I have been a researcher in global health and infectious (parasite) disease epidemiology for over 25 years and have conducted population-based primary epidemiological field research both in Canada and abroad. My Canadian-based research has focused primarily on infections in child and educator populations in the daycare setting and imported and endemic parasite infections in at-risk populations (eg. immigrants, travelers). My global health research activities centre mainly on: 1. deworming control programs in high risk population subgroups (eg. preschool-age children, school-age children and pregnant women); 2. interdisciplinary approaches to the prevention and control of endemic infectious and parasitic diseases; 3. the interrelationship between infection and (mal)nutrition in child populations and women of reproductive age (including pregnant women) and, 4. reducing health inequities in communities of extreme poverty in endemic areas of low-and-middle-income countries.
