Brief Biography

Thomas Eiwegger earned his doctoral degree at the Medical University of Vienna, Austria, where he also completed his paediatric training. He did his post doctoral training in the Swiss Institute of Asthma and Allergy in the group of Cezmi Akdis from 2008 to 2010 and after returned to the Medical University of Vienna where he trained in paediatric allergy and respiratory medicine. Before moving to Sickkids, Eiwegger was Principal Investigator and Associate Professor at the Department of Paediatrics and Adolescent Medicine, Medical University of Vienna, Austria.

Research Interests

Developing and facilitating new concepts in the treatment of food allergy

Eiwegger’s main interests are mechanisms of IgE-mediated allergy. He will focus in particular on a better understanding of the mechanisms of tolerance development to food allergens and markers thereof. Eiwegger will define new treatment approaches by delineating the sequence of events that take place in children that lose their food allergy.
