I work across multiple areas in vaccine discovery and development and have gained strong expertise in the microbiology of infectious diseases and immunology of vaccines for human and veterinary diseases. As a translational scientist, my expertise spans academia and industry, basic science to clinical trials and implementation of vaccine campaigns in different global settings. I have patented multiple inventions in the vaccine space in this time and extensively published in immunology, pharmaceutics/formulation and in behaviour and attitudes surrounding vaccine acceptance. I now focus on developing novel scientific solutions to vaccine accessibility and acceptability issues. Developing needle-free, easier-to-administer delivery systems is critical to addressing financial and logistic constraints in global immunisation programmes One of my research focuses on developing vaccine-based skin patches that do not require cold chain distribution and can be self-administered. In collaboration with clinical pharmacy colleagues, we research Irish parents’ knowledge attitudes and beliefs to vaccination. We developed an evidenced-based interventions to address identified issues in HPV vaccination in Ireland. My published research in this area highlighted to me the need to promote an open dialogue with the public to support their critical evaluation capabilities with respect to implementing public health measures such as vaccination.
