Professor Amanda Leach AM is leader of the Ear Health Research Program, Child Health Division.

Prof Leach has 157 career publications; her 1994 PhD publication (cited by 408) described for the first time that Indigenous infants acquire nasopharyngeal bacterial pathogens within weeks of life and that acquisition predicted onset of otitis media (OM).

Prof Leach led the 6-year NHMRC Centre of Research Excellence in Ear and Hearing Health of Aboriginal and Torres Strait Islander children to 2021. Prof Leach led the update of the 2010 OM Guidelines including an OM app using the highest quality international GRADE approach, also endorsed as a Guideline by the Royal Australian College of General Practitioners. She was NHMRC lead investigator for two vaccine trials (PREVIX_COMBO and PREVIX_BOOST), a study of school readiness (VOICES), and is co-investigator of a CSOM treatment trial (IHEARBETA), two trials for treatment of OM in urban Aboriginal children (WATCH and INFLATE), two new trials of Aboriginal Health Practitioner ear support for Aboriginal children in hospital (Deadly Ears in Deadly Hands), and a trial of Azithromycin before Birth. 

Prof Leach is Joint Chair with Professor Kelvin Kong, for the 5-year Hearing for Learning Initiative – a funding partnership between The Balnaves Foundation, the Northern Territory Government, and the Australian Government. The goal of this stepped-wedge cluster randomised trial of accredited and skills training and employment in 20 communities is to establish local, sustainable, clinical and education expertise to support elimination of social and educational disadvantage caused by ear disease and hearing loss.

In 2011 she won a 6-year NHMRC Senior Research Fellowship which was awarded the inaugural Elizabeth Blackburn Fellowship for top ranking female applicant in the clinical category.

In 2019 Prof Leach won the Telstra NT Business Woman of the Year, and in 2020, Prof Leach was made a Member (AM) of the Order of Australia for significant service to ear disease research, and to Indigenous child health.
