Research Focus

My research focuses on parasite epidemiology and the prevention and control of parasitic diseases worldwide. I have been a researcher in global health and parasite epidemiology for over 30 years, conducting population-based primary epidemiological field research focused on maternal and child health both in Canada and in parasite-endemic countries. Research topics have focused on: deworming control programs in high-risk population subgroups; interdisciplinary approaches to the prevention and control of parasitic diseases; and infection and (mal)nutrition in child populations and pregnant women. As director of the Pan American Health Organization (PAHO)/World Health Organization (WHO) Collaborating Centre for Research and Training in Parasite Epidemiology and Control, based at McGill University, I continue to work with the WHO, PAHO and national governments in developing global guidelines for the prevention and control of various neglected tropical diseases and in promoting health policy focused on reducing the burden of disease attributed to worm infections.
