Research Area(s)

  • Vaccinology and immunology of veterinary species

Academic Credentials

  • BSc. in Biochemistry, High Honour’s, University of Saskatchewan
  • PhD. in Biochemistry, University of Saskatchewan
  • Postdoctoral Fellowship, Vaccine & Infectious Disease Organization, University of Saskatchewan

I have trained (or am in the process of training) 3 Postdoctoral Fellows, 2 Master’s Student,  1 Ph.D. Student, 2 full-time technicians, 6 project students and 3 summer students. I have been involved in teaching undergraduate and graduate student courses at the U of S in the Department of Biochemistry (BIOCH 416.3, BMSC 200.3, BINF 210.3), the Department of Veterinary Microbiology (VTMC-830.3), and ITraP Integrative Seminar Series (VBMS 898.3).

Research Interests

My current research focus involves using intrauterine immunization to promote mucosal immunity, using pig as an animal model. Pigs are ideal because a sow’s cervix is permissive to catheters during standing estrous and they are routinely artificially inseminated using this procedure. Her other research areas include filling the fundamental gap in our knowledge of the permeability of the neonatal piglet gut and to capitalize on its semi-permeable state to develop mucosal vaccines. Dr. Wilson’s areas of expertise include mucosal immunology, neonatal vaccinology, swine immunology, and elucidating mechanism of adjuvant signalling.

 Current Projects:

  • Determine the regional and age-dependent differences in intestinal permeability to macromolecules and maternal cells
  • Intrauterine immunization - a novel approach to induce broad mucosal immunity
  • Development of novel vaccine for newborns against Lawsonia intracellularis: a platform technology
  • Chlamydia trachomatis and Neisseria gonorrhea- animal models and vaccine development
