Dr Niazi is a Lecturer in Environmental Health and a registered member of Environmental Health Australia (EHA), reflecting his commitment to national standards in professional practice and education. His research focuses on environmental risks to human health, with a strong emphasis on environmental pollution monitoring, air quality, and exposure assessment. He has significant laboratory experience spanning microbiology, chemistry, and aerosol science, enabling a multidisciplinary approach to complex environmental health and science challenges.

Dr Niazi collaborates extensively with national partners across Australia and international collaborators in the USA, Europe, and Asia, contributing to impactful, cross-disciplinary research. His work has led to high-impact publications and successful research funding, advancing evidence-based science and informing policy development. His academic and professional contributions continue to shape both research and teaching across a range of scientific disciplines within the School of Science.

Dr Niazi’s research sits at the intersection of atmospheric science, environmental health, and infectious disease control. A key focus of his work is on airborne bioaerosol monitoring, characterisation, and understanding their impacts on human health. He investigates the physical and biological behaviour of aerosols—particularly bioaerosols—in both indoor and outdoor environments.

One major research stream explores how environmental parameters, such as humidity and temperature influence the survival and transmission of airborne viruses. His projects have focused on modelling the survival of airborne viruses in built environments and proposing mitigation strategies to reduce pathogen transmission. Dr Niazi has published extensively on this topic in high-impact journals including Environmental Science & Technology, Science of the Total Environment, and Environmental Pollution. 

Another significant area of his research examines air quality and its health impacts, including population exposure assessments using advanced atmospheric monitoring techniques. His recent research project examines the impact of bushfire emissions on the health of residents in New South Wales.

Dr Niazi’s research directly informs risk mitigation strategies and evidence-based public health policies, particularly in the contexts of climate change, urbanisation, and pandemic preparedness.

Before joining his current role, Dr Niazi completed a three-year postdoctoral fellowship at the International Laboratory for Air Quality and Health (ILAQH), a world-leading centre in atmospheric and air quality research. During this time, he led and contributed to several projects focused on indoor air pollution, airborne pathogen survival and transmission, and the health impacts of airborne contaminants. Notably, he played a key role in developing advanced techniques for measuring airborne pathogens, significantly enhancing the field’s ability to monitor bioaerosol exposure and its associated health risks.
