During her PhD, Erin investigated the impact of zinc on the bacterial pathogen Streptococcus pneumoniae. This work provided fundamental insight into the metabolic and transcriptomic impacts of zinc stress and identified a novel drug repurposing strategy that could be exploited to restore the susceptibility of bacteria to antibiotics.

Erin continues her research on S. 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 carbohydrate metabolism, with a particular interest in the function of bacterial membrane proteins and enzymes. Her research aims to define the mechanisms underlying bacterial nutrient metabolism in the host environment and the adaptation of clinical pneumococcal isolates to specific host sites. Erin also explores the mechanisms by which 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 target these pathways as new treatment strategies against pneumococcal infections.

Erin also works 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 S. pneumoniae biology to the team and has contributed to the invention of a range of next generation vaccine candidates. The current lead candidate, which is capable of providing improved immunogenicity and favourable properties for large-scale manufacture, will be tested in a Phase I clinical trial in late 2022.
