Appointment Status

Dr Tadros graduated from Medical School at Cairo University.

She received her MSC degree and PhD degree from Cairo University in Clinical Pathology, with Medical Microbiology as a subspecialty. 

Dr Tadros worked as a Medical Microbiologist and an Infection Control Consultant at Cairo university Hospitals.

She moved to Canada in 2005 and after obtaining her Medical Counsel of Canada certification, and joined the residency program at University of Toronto medical microbiology department for re-training and obtained her Royal College certification in 2013. 

Dr Tados worked as a Medical Microbiologist at Fraser Health Authority Hospitals, BC and at St. Michael's Hospital, Toronto. She is currently working at Hospital for Sick Children.


Research Synopsis


I have a wide a wide scope of research interests in medical microbiology, including:

  • hospital epidemiology
  • Improving Diagnostics in Mycology
  • Novel methods in bacterial typing such as mass spectrometry
  • Laboratory quality improvement

My research philosophy can be simply summarized in this statement; ‘From bench to bedside’, I am mainly focused on research that can be translated into an improved quality of care for our patients.

Improving diagnostics is a primary area of interest. This includes early and accurate identification of antibiotic resistant organisms using innovative technologies such as newer versions of mass spectrometers, robust software tools, whole genome sequencing and others.

In addition to its potential impact to clinical care and antimicrobial stewardship, my research applies these technological advances to the field of hospital epidemiology.

I am working on novel methods for rapid and accurate cluster analysis of microorganisms. This would impact Infection Control practices and support early identification of outbreaks and perhaps offer a better understanding of the dynamics of transmission of microorganisms between patients and within the hospital environment.
