Research

Tony Walls is a graduate of the University of Otago, having trained in Paediatrics at both Christchurch and Dunedin Hospitals. He trained as a Paediatric Infectious Disease Specialist at the Royal London Hospital and Great Ormond Street Hospital for Sick Children. At this time he completed an M.D. through the University of London, focusing on adenovirus infection in children following bone marrow transplantation.

He has an ongoing clinical interest in the management of infection in immunocompromised children. Before returning to Christchurch he worked as a Consultant at Sydney Children’s Hospital, and was lead clinician for the Paediatric HIV Service.

His research interests include:

  • Kingella infections in preschool children
  • Epidemiology of common childhood infections
  • Optimising antibiotic prescribing in children
  • Impact of vaccinations on global health outcomes for children
  • Teaching Global Health in Paediatrics
