Helen Agus is an Associate Professor in the Discipline of Infectious Diseases and Immunology at the University of Sydney. She has a distinguished career at the institution within the Faculty of Science, where she previously served as a senior lecturer in microbiology in the School of Molecular Bioscience and Chair of the Teaching and Learning Committee. Agus has made substantial contributions to undergraduate education, teaching and coordinating key units including MICR2922 Microbes in Society (Advanced), MIMI2002 Microbes, Infection and Immunity, and courses in virology and infectious diseases. Her involvement extends to curriculum design, strategic planning for microbiology education, and highlighting the value of laboratory practical experience. Administratively, she coordinated programs such as the Bachelor of Medical Science and Bachelor of Psychology, and held the position of Deputy Pro-Dean (Indigenous and Social Inclusion).

Agus's research specializations center on innovative drug delivery systems for respiratory infections, including co-spray dried antibiotics for dry powder lung delivery, liposomal nanoparticles controlling ciprofloxacin uptake and release across respiratory and bronchial epithelia, and laponite clay as a carrier for in situ tetracycline delivery. Additional interests include asthma bronchoconstriction mechanisms, environmental sampling for Cryptococcus neoformans var. gattii, and oral health analyses of saliva buffering capacity, flow rate, lithium content, and caries experience in children. Prominent publications are "Cospray Dried Antibiotics for Dry Powder Lung Delivery" (2008), "Co-spray dried mannitol-ciprofloxacin dry powder inhaler for cystic fibrosis and chronic obstructive pulmonary disease" (2010), "Liposomal Nanoparticles Control the Uptake of Ciprofloxacin Across Respiratory Epithelia" (2012), "Inhaled Liposomal Ciprofloxacin Nanoparticles Control the Release of Antibiotic at the Bronchial Epithelia" (2012), "Deep inspiration volume and the impaired reversal of bronchoconstriction in asthma" (2013), "Laponite clay as a carrier for in situ delivery of tetracycline" (2013), and "Environmental sampling for Cryptococcus neoformans var. gattii from the Blue Mountains National Park, Sydney, Australia" (2002). Her 21 publications have received 763 citations, demonstrating influence in microbiology, infectious diseases, and pharmaceutical sciences.
