Dr. Tron completed his anatomical pathology specialty training at the University of British Columbia. He then completed an MRC research fellowship at McMaster University and a dermatopathology fellowship at Massachusetts General Hospital. His clinical practice is focused on dermatopathology. Dr. Tron has published extensively in the area of molecular mechanisms of skin cancer.
Hasan Ghaffar, MD, FRCPC is head of the Division of Laboratory Hematology at St. Michael’s Hospital and assistant professor in the Department of Laboratory Medicine and Pathobiology at the University of Toronto. He completed residency in Anatomic and Clinical Pathology at Baystate Medical Center/Tufts University School of Medicine in Massachusetts, followed by fellowships in hematopathology at Cornell University and cytopathology at Memorial-Sloan Kettering Cancer Center in New York City. His practice encompasses various aspects of diagnostic hematopathology. He has expertise in lymphoma diagnosis and flow cytometry.
Larissa M. Matukas, MD, FRCPC is head of the division of Microbiology at St. Michael's Hospital. She completed her undergraduate science degree at McGill University in immunology (1995). She obtained her MSc in Immunology of Infectious Diseases from the London School of Hygiene and Tropical Medicine, U.K. (1996). She returned to Toronto to complete her medical degree at the University of Toronto (2001) and her residency training in Internal Medicine (2005), Infectious Diseases (2007) and Medical Microbiology (2007).

Katerina Pavenski, MD, FRCPC (Transfusion Medicine) is a head of the Division of Transfusion Medicine and a medical director of the Blood Conservation and Therapeutic Apheresis Services at St. Michael's Hospital. Her undergraduate training was in Genetics at the University of Manitoba (1997). She obtained her Doctor of Medicine degree from the University of Toronto (2001) and subsequently completed residency training in Internal Medicine (2004) and Adult Clinical Hematology (2006) in Toronto. She then pursued a two-year residency training in Transfusion Medicine at the McMaster University, Hamilton (2006-08). She joined St. Michael's on April 1, 2009. She is an assistant professor in the Department of Pathobiology and Laboratory Medicine. Her research interests include clinical transfusion medicine, transfusion management of massive hemorrhage, patient blood management, TTP and other thrombotic microangiopathies, as well as therapeutic apheresis. She is the chair of St. Michael's Hospital Transfusion Committee, an immediate past chair and member of the Ontario Blood Advisory Committee, a member of the National Advisory Committee on Blood and Blood Products. She was the chair of the local organizing committee of the 35th International Congress of the International Society of Blood Transfusion (June 2018, Toronto) and served on the board of directors of the Canadian Society for Transfusion Medicine.
Daniel Beriault, MSc, PhD, FCACB is head of the Division of Biochemistry at St. Michael’s Hospital and assistant professor of Laboratory Medicine and Pathobiology at the University of Toronto. He obtained his MSc in the Department of Biophysics at the University of Guelph and his PhD in biochemistry at McMaster University. Dr. Beriault completed his post-doctoral fellowship in clinical biochemistry at the University of Toronto and is a fellow of the Canadian Academy of Clinical Biochemists (FCACB). His areas of research interest include diabetes and disease biomarkers. He has expertise in endocrinology and toxicology testing.
Catherine Streutker, MD, FRCPC obtained her BSc at the University of Waterloo in the co-operative program in Biochemistry (1989). She then earned a master's degree in Clinical Biochemistry at the University of Toronto (1991), training under the supervision of Dr. Daniel Drucker. On completion of her master's degree, she entered medical school at the University of Toronto and graduated in 1994. She entered the Anatomic Pathology Residency program at the University of Toronto and wrote the Royal College Exam in 1999. After this, she completed a two-year fellowship in Gastrointestinal Pathology with Dr. R.H. Riddell and Dr. K. Croitoru at McMaster University in Hamilton. In 2001, she joined the Department of Laboratory Medicine and Pathobiology at the University of Toronto and began her appointment as a staff pathologist at St. Michael's Hospital. She specializes in gastrointestinal pathology, particularly upper gastrointestinal tract malignancies, but considers herself a general surgical pathologist. She is the director of Pathology at St. Michael's Hospital.
Dr. Ramzi Fattouh, PhD, FCCM is a Clinical Microbiologist and the Director of Molecular Diagnostis at St. Michael’s Hospital.
