Dr Simor graduated with a medical degree from the University of Toronto in 1976, and completed Royal College fellowship training in internal medicine, infectious diseases, and medical microbiology.
He has worked at Sunnybrook Health Sciences Centre since 1993.
Dr Simor is recognized nationally and internationally as a leader in the field of hospital epidemiology.
He has received research funding from peer-reviewed and industry-based granting agencies.
He has published a large number of papers in scientific journals, and he is on the Editorial Board of the journal, Infection Control and Hospital Epidemiology, and is an Associate Editor for the Canadian Journal of Infectious Diseases and Medical Microbiology.
His primary research interests include:
- antimicrobial resistance
- hospital-acquired infections
- the application of molecular technologies to the diagnosis and management of infectious diseases.
Dr Simor has received several teaching award from the university, and in 2005 was selected to receive the Distinguished Service Award from the university’s Department of Laboratory Medicine & Pathobiology.
He has also received a Canadian Hospital Infection Control Association Award of Merit for service in the advancement of infection prevention and control.
The organism of primary concern is methicillin-resistant Staphylococcus aureus (MRSA), but I am also interested in vancomycin-resistant enterococci (VRE), multidrug-resistant gram-negative bacilli, and Clostridium difficile.
My research is primarily clinical and epidemiological in understanding the epidemiology, risks, and outcomes associated with important healthcare-associated infections, and infections caused by antibiotic-resistant organisms such as methicillin-resistant Staphylococcus aureus (MRSA) and Clostridium difficile.
As such, I am a lead investigator in a network of Canadian hospitals known as the Canadian Nosocomial Infection Surveillance Program (CNISP), which has been conducting prospective surveillance for a variety of important healthcare-related infections since 1995.
My laboratory-based investigations involve studies of mechanisms of resistance to antimicrobial agents, as well as evaluations of methods used to improve the detection of antibiotic resistance.
I am also interested in the application of molecular technology (nucleic acid amplification test methods and molecular typing) to the diagnosis, management, and prevention of infectious diseases.
