 What brought me to MUN? What keeps me at MUN?

I came to MUN from Dalhousie in 2010.  I am originally from Halifax.  I like the independence I have here, to develop my research and teaching program.  The highlights of living in St. John’s are the music, and the East Coast Trail.

Peter Daley is an infectious diseases physician and medical microbiologist.  

His Internal Medicine residency was completed at Queen's University and Infectious Diseases fellowship training at the University of Calgary. 

He completed a Diploma in Tropical Medicine and Hygiene at the Gorgas Memorial Institute in Lima, Peru.  He went on to Medical Microbiology fellowship training at McMaster University, where he completed a research fellowship in molecular mycobacteriology.   

During this time he developed a research interest in Tuberculosis, which lead him to India where he lived and worked for three years at the Infectious Diseases Training and Research Center at the Christian Medical College Vellore in Tamil Nadu.  He has published in Tuberculosis diagnosis, treatment and epidemiology. 

He completed his Masters in Clinical Epidemiology at Memorial University. Current research interests include evaluation of diagnostic tests including algorithms, net reclassification improvement and clinical impact of diagnostic tests.  He is also active in clinical trials and observational studies.  He is accepting selected Masters in Clinical Epidemiology students and resident research projects.   

Peter is assistant professor of Medicine at Memorial University in St. John's, Newfoundland, Canada, where he is regional director of the medical microbiology laboratory and consultant in infectious diseases.  He is active in the Royal College of Physicians Medical Microbiology Specialty Committee and Examination Committee and in the Association of Medical Microbiology and Infectious Diseases Canada.   

He has published 18 international publications and four book chapters and has been co-investigator on two successful CIHR grants.

Research/Teaching Summary:

My primary research interest is diagnosis of bacterial infections.  I am also involved in clinical trials of antibiotic therapy and epidemiology of bacterial infections.  I worked in India for three years on tuberculosis diagnosis and treatment, and I have interest reducing the impact of bacterial infections globally.  I am active in corporate and investigator-driven clinical trials and supervise Masters students in Clinical Epidemiology.   

I teach medical microbiology to undergraduates and infectious diseases to residents.  I teach diagnostic epidemiology to graduate students.  I help coordinate national conferences with the Association of Medical Microbiology and Infectious Diseases Canada, and sit on the examination committee in Medical Microbiology at the Royal College of Physicians Canada.
