In addition, he is a professor of Laboratory Medicine and Pathobiology at the University of Toronto. From 2009 to 2014, he was the clinical and academic head of the Department of Pathology and Molecular Medicine at Queen’s University in Kingston, Ontario. Dr. Tron also served as chair and chief in the Department of Laboratory Medicine and Pathology at the University of Alberta. He is a medical graduate of the University of Alberta. 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). She joined St. Michael's Hospital in October 2007. Her research interests include antimicrobial resistance, quality improvement and medical education.

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 management of acquired coagulopathies, therapeutic apheresis and blood management. She is the chair of St. Michael's Hospital Transfusion Committee, a member of Ontario Blood Advisory Committee (OBAC), a member of National Advisory Committee on Blood and Blood Products (NAC) and is 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. Dr. Fattouh received his doctorate in Medical Sciences from McMaster University. He went on to complete a postdoctoral fellowship in Clinical Microbiology from the University of Toronto in 2016, and is a Fellow of the Canadian College of Microbiologists (CCM). Dr. Fattouh joined St. Michael’s Hospital as a Clinical Microbiologist and the Director of the Molecular Diagnostics Laboratory in 2017. Over the course of his studies he has published numerous peer-reviewed articles, reviews and book chapters and has presented his findings at several national and international conferences. His current research interests include i) antimicrobial resistance and stewardship, and ii) the development of novel molecular-based diagnostics including genome sequencing.
