Dr. Gregory Tyrrell serves as a Professor in the Department of Laboratory Medicine and Pathology within the University of Alberta's Faculty of Medicine & Dentistry. He concurrently works as a Clinical Microbiologist at the Alberta Provincial Laboratory for Public Health (ProvLAB), where he has overseen critical programs including the Level 3 laboratory, TB program, and Streptococcal program for over 22 years. His leadership extends to roles as Edmonton Zone Clinical Department Section Chief for Medical Microbiology and Divisional Director for the Division of Diagnostic and Applied Microbiology.
His educational journey began with a BSc and MSc from the University of Alberta, followed by a PhD at the University of Toronto. He completed a Clinical Microbiology Fellowship at the same institution and gained early career experience at Dalhousie University in Halifax before returning to Edmonton.
Dr. Tyrrell's research centers on the epidemiology of streptococcal diseases, with particular expertise in Streptococcus pneumoniae, Group A and Group B streptococci. His work spans outbreak investigation in First Nations communities, antimicrobial resistance surveillance, and tuberculosis epidemiology. He actively contributes to national vaccine advisory committees for pneumococcal and meningococcal vaccines, bridging laboratory science with public health policy.
Analysis of his recent publications reveals a dominant focus on genomic epidemiology of bacterial pathogens, particularly tracking serotype shifts in streptococci through whole-genome sequencing. His research integrates provincial surveillance data from Alberta with national networks like IMPACT, emphasizing vulnerable populations and vaccine impact assessment. Collaborative work spans infectious disease modeling, antimicrobial resistance mechanisms, and zoonotic transmission pathways.
Dr. Tyrrell has trained numerous undergraduate and graduate students alongside medical residents in Medical Microbiology, emphasizing diagnostic microbiology and outbreak response. His laboratory leadership encompasses the Provincial Streptococcal Reference Laboratory and TB program, directly informing Alberta's public health interventions for bacterial diseases.
He directs ProvLAB's Level 3 laboratory operations and Streptococcal program, which monitors invasive bacterial diseases across Alberta with special attention to northern communities. His team conducts molecular characterization of pathogens for outbreak investigation and contributes to national surveillance systems tracking vaccine-preventable diseases.
