My research focuses on measuring the burden and improving the care of parasitic diseases such as strongyloidiasis and tegumentary leishmaniasis in vulnerable populations, with a focus on migrants and immunocompromised individuals. I am currently conducting studies on Strongyloides knowledge and awareness among Canadian physicians to build educational tools that will improve Strongyloides screening in the high-risk population. I am also studying the prevalence of Strongyloides in the immunocompromised population in non-endemic countries and the best screening strategy in that population. In collaboration with Universidad Peruana Cayetano Heredia in Lima, Peru, I am studying the response to Strongyloides stercoralis treatment in the HTLV-1 population. I am also interested in the management of tegumentary leishmaniasis in travellers and migrants. One of the ultimate goals of my research is to increase knowledge and awareness of neglected tropical diseases such as strongyloidiasis and tegumentary leishmaniasis among physicians in non-endemic countries. Another is to determine the most cost-effective strategies for Strongyloides screening in the high-risk population and the best treatment in the immunocompromised population and HTLV-1 co-infected, to inform evidence-based preventive clinical care and management guidelines.
