Dr. Daniel Gregson M.D. FRCPC
I am a graduate from the Medical School at the University of Toronto in the class of 1983. My training in Internal Medicine, Infectious Disease, and Medical Microbiology was done in the post-graduate training programs there. After attaining Royal College specialty certification and certificates of special competence these fields and US board cerification in Internal Medicine and Infectious Diseases, I moved to the University of Western Ontario (now known as Western University) in London, Ontario, Canada to work as an Infectious Diseases consultant and Medical Microbiologist at St. Joseph's Health Center. in conjunction with my colleague Dr. Ole Hammerberg, we ran a diagnostic bacteriology and virology service and provided both inpatient and outpatient consultations to the hospital community. In addition, I was heavily involved with the provision HIV care prior to the introduction of highly active anti-retroviral therapy.

In 2000, I was recruited to Calgary to work with the regions Division of Medical Microbiology in the Department of Pathology and Laboratory Medicine, and the Division of Infectious Diseases in the department of Medicine. I currently associate professor in the Department of Pathology and Laboratory Medicine at the University of Calgary, cross appointed to the Department of Medicine. My administrative roles include being the Section Chief of Medical Microbiology in the Calgary zone of Alberta Health Services and the Division Head of Medical Microbiology in the Department of Pathology and Laboratory Medicine at the University of Calgary.

I currently honored to be the President-Elect of the Association of Medical Microbiology and Infectious Diseases Canada.

My current research interests are related to the etiology and outcomes of invasive infections in humans and laboratory methods for the rapid diagnosis of infection, and the use of medical informatics in microbiology and infectious disease.
