Dr. Jennie Johnstone
Infection Prevention and Control
"Reducing health care-associated infections is an essential component to improving the health of Ontarians. By working at PHO, I am able to generate new knowledge about health care-associated infections through research and help translate these findings into practice and policy through knowledge to action initiatives."
