Head, Infectious Disease Implementation
BMBS DTMH GDipClinEpid PhD FRACP
Professor Tom Snelling is a paediatric infectious diseases physician at the Perth Children’s Hospital, NHMRC Career Development Fellow and Head of the Infectious Disease Implementation research team as part of Telethon Kids Institute's Wesfarmers Centre of Vaccines & Infectious Diseases.
His research addresses the implementation of health policy and clinical practice, in particular the evaluation of vaccination and other public health strategies to minimise the burden of childhood infectious diseases. This work integrates clinical trials with case-control and cohort studies and disease modelling. His current work is investigating how best to prevent and treat gastroenteritis, pneumonia, pertussis and other lower respiratory infections, and congenital rubella. Tom was awarded a Medical Research Future Fund (MRFF) grant from NHMRC earlier this year and leads this Bayesian Evidence-Adaptive Trial to optimise management of cystic fibrosis.
His work has a strong focus on Aboriginal and international child health. He is also investigating the safety of vaccination in early childhood.
