Areas of Research

Area of Focus
  • HPV vaccination in First Nations
  • Enhanced Recover After Surgery (ERAS)
Summary of Research


Enhanced Recovery After Surgery (ERAS) is an evidence based multimodal perioperative care program which aims to improve cancer patients’ outcomes by minimizing the stress response to surgery. I am interested in studying the clinical, physiological and health system impacts of ERAS on patients undergoing surgery for cancer in Alberta.


Co-developed with Elders from the Tsuu T’ina and Stoney First Nations, the Enhancing HPV Vaccination In First Nations Populations in Alberta (EHVINA) Study received $1,248,400 in funding over five years from Alberta Innovates Health Solutions’ Cancer Prevention Research Opportunity, through the Alberta Cancer Prevention Legacy Fund. Our team is conducting research aimed at increasing HPV vaccination rates among FN people living on-reserve in Alberta. The objectives of this work include:

  • establish baseline HPV vaccination rates
  • identify and validate the known barriers and supports to HPV vaccination
  • map identified barriers and supports onto a theory-informed, context- and culturally- secure knowledge translation (KT) intervention to increase HPV vaccination uptake within Alberta FN communities
