I am a Scientia Associate Professor and Deputy Director of Research at School of Optometry and Vision Science, UNSW, Sydney. I lead a program of research into behavioural and host immune susceptibility to eye infections at UNSW and Westmead Institute for Medical Research. I have Honorary appointments with University of Sydney and University College London. I am the inaugural Chair of Australian Standards Contact Lens Committee and serve as an International Standards Organization Expert since 2019.  I am Topical Editor of 4 leading Optometry journals, an elected Council Member of the International Society of Contact Lens Researchers, and British Contact Lens Association Global Champion.  I convene a UNSW Optometry Clinical Masters course (80 students each) and am the Alumni Event Co-Coordinator.

The primary goal of my research is to develop diagnostic biomarkers and interventions to decrease the incidence and morbidity of conditions that disrupt homeostasis of the cornea. These conditions include corneal infection (microbial keratitis) and limbal stem cell dysfunction in contact lens wearers.  

Research Aims:  

  • Understand the host immune and pathogen interaction in corneal infection to provide direction for better management and biologics discovery 
  • Prevention of contact lens related infections and quality of life of patients
  • Determine markers of limbal stem cell dysfunction in contact lens wearers
  • Involve and engage corneal disease patients, carers and relatives in research and support networks that will enhance their quality of life and provide targeted direction for research 

Research Interests:

  • Genetic susceptibility to cornea infection
  • Anterior eye disease immunology
  • Microbiology
  • Epidemiology
  • Quality of life
  • Limbal stem cell disease in contact lens wear
  • Patient involvement in research.

Current Projects:

  • Host immune response to bacterial keratitis: tear, corneal gene expression, genetics
  • Nanodiagnosis of corneal infection
  • Prevention of corneal infection in contact lens wear
  • Quality of life and economic impact of keratitis 
  • Limbal stem cell dysfunction in contact lens wearers 
  • Patient support and engagement in research
