Fun fact about me 

I have a comic book collection.

I love working with children and their families because 
I enjoy listening to all the giggling.

Research interests 

Children with lung diseases, such as asthma and cystic fibrosis, have excessive inflammation in their lungs. This often limits their ability to be physically active. I study how to calm down lung inflammation, boost immune defences, and improve physical performance. In our laboratory we are attempting to increase natural immunity to respiratory viral infections, to prevent people with chronic lung disease from becoming sicker when they catch a cold. In clinical research we are examining a new technique to measure lung function in young infants known as oscillometry. We continue to study exercise ability and the factors limiting exercise in children with chronic disease. 

Research foci 
  • Chronic lung disease; 
  • Anti-viral defense; 
  • Innate immunity; 
  • Exercise physiology; 
  • Nutrtion 

Cystic fibrosis (CF), asthma, immune modulation, physical activity, translational research
