Brief Biography

Dr. Floh graduated from the University of Toronto medical school in 2001 before commencing paediatric training in the McMaster Children’s Hospital in Hamilton.   He returned to The Hospital for Sick Children for fellowship training in paediatric cardiology and paediatric critical care medicine, earning accreditation through the Royal College of Physicians and Surgeons in both disciplines. Dr. Floh pursued further research training, being awarded the Harris-Kassie research fellowship, through the Labatt Family Heart Centre, and enrolling into a Masters degree in epidemiology through the Health Policy, Management, and Evaluation Institute at the University of Toronto.

Dr. Floh joined the Department of Critical Care Medicine July 2013 and is a staff physician with the Department..  His clinical responsibilities include attending in the cardiac critical care unit and as a physician member of the Single Ventricle team.  His research has focused primarily on the study of the pathophysiology of children following bypass heart surgery and their related outcomes.  He has worked closely with Dr. Steven Schwartz investigating the role of sugar, inflammation, cardiac output and nutrition in surgical outcomes.  His Masters thesis also explores the role of inflammation and cardiac output on acute kidney injury in these susceptible children.
