Teaching Interest

Teaching activities are generally grouped into four general areas:

  •  Hospital and community Medical Microbiology laboratory and general hospital laboratory education rounds. Presented to the technical and professional staff on range of topics, eg. pandemic influenza, SARS, Listeria, MALDI-TOF, etc.
  • Presentations to hospital or community laboratory groups outside of the laboratory setting, eg. Medicine rounds, committee education sessions, journal clubs, pharmacy, etc. Topics include antibiograms, hand hygiene, resistant organisms, etc.
  • Presentations at organized meetings and conferences, eg. AMMI-Canada annual conference, BCSLS Congress, Fraser Health education days, etc.
  • Interactions with UBC medical students and residents, eg. yearly Host Defenses and Immunity (HDI) laboratory for the first year medical students, electives with Medical Microbiology Residents and medical students at Royal Columbian Hospital, participation on the Medical Microbiology Residency Training Committee, consultations/interaction with the clinical teaching unit (CTU) residents at Royal Columbian Hospital.
