Dr. Dufresne is a medical specialist certified in medical microbiology and infectious diseases. He has expertise in infectious diseases in immunocompromised hosts and medical mycology.

Research Unit

Dr. Dufresne’s research focuses on the epidemiology, diagnosis and treatment of infectious diseases associated with cancer and transplantation, with an emphasis on invasive fungal infections. His research activities include both laboratory and clinical/epidemiological components. Dr. Dufresne is interested in the development and optimization of fungal infection diagnostics. He also studies the incidence and risk factors of a number of opportunistic infections, including invasive aspergillosis and invasive candidiasis. He is also involved in clinical trials evaluating new antimicrobial agents to prevent and treat opportunistic infections.
