Research Interests

  • Identify the underlying mechanisms of CD8+ T-cell dysfunction in HCV mono- and HIV-HCV co-infection. The function of CD8+ T-cells in the blood and liver are being evaluated. Both host and viral factors that contribute to bulk CD8+ T-cell impairment are being studied.
  • Evaluate innate and adaptive immunity interactions in HCV infection, specifically between macrophage subsets, liver-resident macrophages (Kupffer cells) and CD8+ T-cells.
  • Evaluate the effects of chronic HCV infection on responses to routine vaccination (e.g. seasonal flu and Hepatitis B vaccines).
  • Explore the therapeutic potential of soluble cytokine receptors in the prevention and treatment of disease.

Brief Biography

Dr. Crawley has been with the Chronic Diseases Program at the Ottawa Hospital Research Institute since April 2012. In addition to being a Scientist with the OHRI, she is also an Assistant Professor at the University of Ottawa and an Adjust Professor at Carleton University, where she teaches immunology at the undergraduate, graduate and medical school levels. She teaches these courses in both English and French. Dr. Crawley has earned 2 salary awards: a CIHR New Investigator Award and an Ontario HIV Treatment Network (OHTN) Junior Investigator Development Award. Her research is funded by the OHTN, Canadian Foundation of AIDS Research and the J.P. Bickell Medical Research Foundation.

Dr. Crawley received a B.Sc. in Microbiology and Immunology from McGill University in Montreal, Quebec (Canada) in 1999. In 2004 she completed a Ph.D. in Immunology with Dr. Bruce N. Wilkie in the Dept. of Pathobiology at the University of Guelph’s Ontario Veterinary College (Guelph, Ontario, Canada). Dr. Crawley then trained as a postdoctoral fellow in Dr. Jonathan B. Angel’s laboratory at the Ottawa Hospital Research Institute, and published 10 peer-reviewed scientific research and review articles on the immunopathogenesis of HIV infection. Dr. Crawley was funded by an Ontario HIV Treatment Network (OHTN) Fellowship award and awarded a University of Ottawa Faculty of Medicine Postdoctoral Award of Excellence (2007).
