Brief Biography

Dr. Theo Moraes graduated from medical school in 1997 (Toronto) and then completed his paediatric residency (Kingston) and paediatric respirology fellowship (Toronto) before pursuing his PhD in the laboratory of Dr. Gregory Downey. His postdoctoral training was done in Dr. Tania Watts' lab in the area of T cell immunity to influenza infection.

Research Interests

The Morales lab is broadly interested in viral inflammation in the lung. This type of inflammation is an important health concern, especially in the paediatric population. Adverse effects are related not only to the acute consequences associated with viral infection but also the downstream effects that may be related to a virally altered immune system.

Specifically, Morales and his team are currently studying the immune response to respiratory syncytial virus (RSV) and mechanisms to enhance protection from infection.
