Biofilm formation in bacterial pathogens
Short Biography

I received a Bachelor of Science in Agriculture from McGill University. During this degree, I started my research training by sequencing a small plasmid found in the ruminant pathogen, Histophilus somni. For my MSc, I worked on the same pathogen but studied its ability to acquire iron from haemoglobin. I then moved to Dalhousie University in Halifax to do my PhD on an essential two-component signal transduction system found in the dental pathogen, Streptococcus mutans. After completing my PhD, I started my postdoctoral training at the Faculté de médecine vétérinaire at the Université de Montréal to study biofilm formation in different pathogens important to public health and veterinary medicine. After a short stay at McGill University as a visiting researcher, I moved to Paris (France) and was hired at the Institut Pasteur as a research associate to characterize biofilms formed by the enteric pathogen, Clostridioides difficile.

Throughout my post-secondary education and research training, I took an active interest in teaching and mentoring undergraduate and graduate students. Overall, I have supervised 15 undergraduate projects, 1 graduate project and taught classes to undergraduate, graduate and professional students as a guest or sessional lecturer.
