Dr Sacha Stelzer-Braid is a Senior Postdoctoral Scientist in the Virology Research Lab at University of New South Wales/Prince of Wales Hospital. Dr Stelzer-Braid’s research interests include:
- Transmission modes of respiratory viruses including SARS-CoV-2
- Surveillance of enterovirus and SARS-CoV-2 for emerging strains, using next-generation sequencing
- Using point-of-care tests (POCT) to improve clinical outcomes for patients
- Role of respiratory viruses in exacerbation of chronic airway diseases including asthma and cystic fibrosis (CF)
- Developing novel sampling and diagnostic methods for emerging viruses.

Dr Stelzer-Braid is currently working on studies involving whole-genome next-generation sequencing of SARS-CoV-2 and enterovirus from around NSW, and assessing new point-of-care tests through the UNSW Centre for Research Excellence “Integrated Systems for Epidemic Response (ISER)”. She has given expert opinions in the media around SARS-CoV-2 transmission, survival of the virus on surfaces, and cleaning your home for coronavirus e.g https://www.abc.net.au/news/science/2020-04-18/which-surfaces-harbour-coronavirus/12157080; http://medicalrepublic.com.au/is-sars-cov-2-an-oddball-virus-we-asked-the-experts/27528.
Dr. Stelzer-Braid lectures at the University of New South Wales and the University of Technology Sydney. She is interested in new methods of education and teaching to engage students in the lecture theatre and laboratory and has completed the Foundations of University Learning and Teaching (FULT) course (UNSW) and Learning to Teach Online MOOC (Coursera).
She also enjoys inspiring budding scientists through the CSIRO STEM Professionals in Schools program (in partnership with Lucas Heights Community School) and is passionate about encouraging girls to pursue STEM careers.
Dr. Stelzer-Braid was recently awarded a Franklin Women COVID Carer’s Support Scholarship 2020. She was selected for a UNSW place in the 2019 Franklin Women/Serendis Mentoring program and awarded the Communicable Diseases Network of Australia Observership. She is a member of Franklin Women, the Australian Society for Microbiology, and the Australasian Virology Society.
