My research has focused on the epidemiology of H pylori infection. I’ve directed research projects in Colombia, the US/Mexico border region, and Arctic Canada. My published research on H pylori infection has been cited in over 500 publications catalogued by the Science Citation Index. Upon joining the Centre for Excellence in Gastrointestinal Inflammation and Immunity Research (CEGIIR) at the University of Alberta in 2005, I united colleagues to conduct research aimed at answering questions about health risks from H pylori infection posed by residents of Aboriginal communities in northern Canada and their health care providers. This team includes scientists from various disciplines (epidemiology, anthropology, policy sciences, microbiology, pathology, gastroenterology), clinicians, health officials and community leaders. As a starting point, we initiated the Aklavik H pylori Project. This community-driven research led to the formation of the Canadian North Helicobacter pylori (CANHelp) Working Group, which I direct, and which links Alberta scientists and clinicians with health authorities and community leaders in the Yukon and Northwest Territories. Current goals are to: 1) Obtain representative data from northern Canadian communities for informing regional public health strategies aimed at reducing health risks from H pylori infection; 2) Conduct policy analysis to identify cost-effective and culturally appropriate H pylori management strategies; 3) Develop knowledge exchange strategies that help community members and their health care providers understand H pylori health risks as well as currently available solutions and unsolved challenges for reducing these health risks.
