John Merlino

Dr. John Merlino is an Honorary Associate and Adjunct Senior Lecturer at the University of Sydney's Central Clinical School, Department of Infectious Diseases and Immunology. He holds dual affiliations with NSW Health Pathology (Principal Scientist in Microbiology and Infectious Diseases) and Concord Repatriation General Hospital. His academic background includes a PhD in Medicine from the University of Sydney, with additional qualifications such as FASM (Fellow of the Australian Society for Microbiology) and FFSc(RCPA) (Fellow of the Faculty of Science, Royal College of Pathologists of Australasia).

Dr. Merlino's research focuses on antimicrobial resistance, clinical bacteriology, molecular epidemiology, and diagnostic microbiology. He has contributed to studies on pathogens like Staphylococci, Acinetobacter, Salmonella, and Haemophilus influenzae, emphasizing resistance mechanisms and susceptibility testing methodologies. His work bridges clinical practice and laboratory science, addressing critical challenges in infection control and antibiotic stewardship.

Teaching responsibilities include lectures on antimicrobial resistance, bacteriology, and molecular diagnostics at the University of Sydney. He serves as an examiner for the Royal College of Pathologists of Australasia's microbiology and infectious diseases fellowship exams. His professional roles include past service as a Scientific Adviser to Australia's Department of Health and Ageing and current involvement in NSW Health's pathology system.

Key themes in his research include infection prevention, pathogen identification, and the molecular basis of resistance. His publications emphasize practical applications of diagnostic tools and antibiotic susceptibility testing, with a focus on global health implications of emerging pathogens and resistance patterns.

Laboratory work is conducted through NSW Health Pathology's Microbiology and Infectious Diseases department, where he leads investigations into clinical isolates and contributes to improving diagnostic accuracy and patient outcomes. Collaborations span academic institutions and healthcare networks in Australia, focusing on translational research and public health initiatives.
