Don Sheppard


  • Fellow
  • Fungal Kingdom: Threats & Opportunities




Don Sheppard is an infectious diseases physician and medical microbiologist who he leads the Medical Mycology laboratory and practices clinical infectious diseases at the McGill University Health Centre.

He is primarily interested in human fungal disease, particularly invasive aspergillosis in the immunocompromised host. Sheppard’s research interests focus on elucidating how the fungal pathogen Aspergillus fumigatus causes human disease and developing new therapeutics for these infections. His research group has discovered the molecular mechanism by which Aspergillus forms biofilms and is pursuing antifungal therapies that interfere with this process.
