Erin has a background in molecular and translational microbiology, with a focus on developing new ways of preventing and treating bacterial diseases. With antibiotic resistant superbugs projected to kill 10 million people each year by 2050, new ways of combatting disease are urgently required. A key focus for Erin's early research was the study of the impact of zinc, both nutritional and as a therapeutic, against bacterial pathogens. This work has provided fundamental insight into the metabolic and transcriptomic impacts of zinc on bacteria and identified a novel drug repurposing strategy that could be used to restore the susceptibility of bacteria to antibiotics. These findings have the potential to extend the shelf life of commonly used antibiotics.
Erin continues her research on Streptococcus pneumoniae in her current role as post-doctoral researcher in the Research Centre for Infectious Diseases. By combining her microbiology and biochemistry expertise, Erin investigates pneumococcal virulence and metabolism, with a particular interest in the function of bacterial membrane proteins and enzymes. Her research aims to define the mechanisms underlying bacterial behaviour in the host environment and the adaptation of pneumococci to specific host sites. In 2021, Erin was awarded a Channel 7 Children's Research Foundation grant to explore how these bacteria signal to and communicate with neighbouring bacteria and the host. Together, this research aims to contribute to the understanding of pneumococal biology and ultimately exploit these pathways as new treatment strategies.
Erin also has an interest in the development of new vaccines to address emerging and existing pathogens that threaten global health and biosecurity. Since 2019 Erin has worked closely with the R&D team at GPN vaccines Ltd in the development of a whole cell pneumococcal vaccine. This serotype-independent vaccine aims to address the major shortcomings of the currently used vaccines, including the serotype selection and high cost of manufacture. Erin brings her knowledge of fundamental S. pneumoniae biology to the team and has contributed to the design and preclinical testing of next generation vaccine candidates, including the current lead candidate (Gamma-PN3), which is capable of providing improved immunogenicity and has favourable properties for large-scale manufacture. This vaccine will be tested in a first-in-human Phase 1 clinical trial in January 2023.
Erin is passionate about translating research findings from the laboratory bench into commercial products that can have a positive impact on patients and public health. In 2022, Erin was awarded the QUT Bridge Pitch Competition ($10,000) for her medical innovation presentation and a Bridge Industry Fellowship ($10,000). In this fellowship, Erin is gaining experience working with GPN Vaccines on business strategy and IP development for new vaccines.
