Charity Evans Associate Professor

Director, Continuing Professional Development for Pharmacy Professionals and medSask

E3130 Health Sciences


Dr. Charity Evans is an assistant professor of Pharmacy, teaching in the areas of evidence-based medicine, research methods, and contraception. She received her BSP and PhD in Pharmacy from the University of Saskatchewan and completed a postdoctoral fellowship at the University of British Columbia. She has recently taken on the role of director of the Continuing Professional Development for Pharmacists program and is a member of the Board of Directors of the Multiple Sclerosis Society of Canada, Saskatchewan division.


Dr. Evans’s research program focuses on multiple sclerosis (MS), with a particular emphasis on the epidemiology and pharmacoepidemiology of the disease. She is a principal investigator with the Cameco MS Neurosciences Research Centre. Current research projects and collaborations are funded by the MS Society of Canada and the National MS Society (U.S.) and include:

  • Multi-province study examining the impact of adherence to the MS disease-modifying therapies on clinical and health care utilization outcomes
  • Multi-province study examining the potential existence of a prodromal phase in MS
  • Assessing safety and monitoring in patients taking oral multiple sclerosis treatments
