Dr. Tanja Gonska is an Associate Professor in the Division of Paediatric Gastroenterology, Hepatology and Nutrition, University of Toronto, with a subspecialty focus on paediatric pancreas diseases and cystic fibrosis. She holds appointments in the Institute of Medical Science and as a Senior Associate Scientist in the SickKids Research Institute. Following medical school in Muenster, Germany, she completed her paediatric residency training at the Children’s Hospital in Freiburg, Germany, with a focus on paediatric pulmonology, allergology and cystic fibrosis. Attracted by the renowned cystic fibrosis (CF) group, she came to Toronto for a fellowship in paediatric gastroenterology, hepatology and nutrition at SickKids. Her mentors were Professors Peter Durie, Christine Bear and Paul Quinton. Dr. Gonska continued her academic career in paediatric pancreatology and cystic fibrosis as a Staff Physician at SickKids. Next to her involvement in an international consortium to advance the knowledge in paediatric pancreatitis, her main research interest is focused on increasing our understanding of transepithelial ion and fluid transport in the airway and intestine. In addition, her innovative approach to develop new measures of functional outcome supports current strategies to cure cystic fibrosis.
