Rate My Professor Tanya Golubchik

Associate Professor Tanya Golubchik is a computational microbiologist serving as NHMRC Principal Research Fellow at the Sydney Institute for Infectious Diseases, School of Medical Sciences, Faculty of Medicine and Health, University of Sydney. She began her academic journey at the University of Sydney, majoring in biology and computer science, and earned her PhD in molecular biology from the institution. Following her doctorate, Golubchik held a postdoctoral position at the Department of Statistics, University of Oxford, employing genotyping to track pneumococcal vaccine escape variants. She subsequently worked at the Nuffield Department of Medicine, Oxford, analyzing within-host diversity, evolution, and transmission of bacterial pathogens such as Staphylococcus aureus using next-generation sequencing data. She contributed to the Modernising Medical Microbiology consortium, pioneering early microbial genomic epidemiology systems. From 2016 to 2021, based at Oxford's Big Data Institute, she collaborated with the PANGEA-HIV consortium on HIV genomics, developing a machine learning model for subtype-agnostic time-since-infection estimates, and advanced targeted metagenomics through the Oxford Viromics group. During the COVID-19 pandemic, she led SARS-CoV-2 sequencing analyses for the COG-UK Consortium. Golubchik returned to the University of Sydney in 2022.

Her research applies modern genomics to investigate pathogen interactions, evolution, and effects on human hosts to advance healthcare. Her team examines viral and bacterial genetic diversity from intra-host variants to multi-species dynamics, pioneering targeted metagenomics for co-sequencing multiple pathogens and tools like Castanet and DAMPA. Ongoing projects include NIHR-funded diagnostic metagenomics for bloodborne pathogens, Gates Foundation-supported EMPOWER study on reproductive health infections, and NHMRC-funded COSMOS for mosquito-borne pathogens. She secured an NHMRC Leadership 3 Investigator Grant valued at $2,769,655 for 'Expanding the field of view: from pathogen-centric to syndromic genomics.' Key publications encompass 'SARS-CoV-2 within-host diversity and transmission' (2021), 'Efficacy of ChAdOx1 nCoV-19 vaccine against hospitalisation' (2021), 'Whole-genome sequencing for prediction of Clostridium difficile' (2015), 'HIV-phyloTSI: subtype-independent estimation of time since infection' (2025), and 'Castanet: a pipeline for rapid analysis of targeted multi-pathogen data' (2024). With 14,731 citations and an h-index of 51 on Google Scholar, her contributions have profoundly shaped microbial genomics, epidemiology, and public health microbiology.
