Broadly Dr Hinds research has been focused on bacterial pathogen genomics for the past 25 years, using genomics technologies, such as microarrays, next-generation sequencing and point-of-care devices, to address important questions in bacterial pathogenesis and diagnosis. A key aspect of this effort has been the translational nature of the research, applying basic research discoveries and genomic technologies to real-time problems, for example, monitoring vaccine trials or informing patient treatment.
The majority of current research activity has been developed and established over the past 10 years, using microarrays as an effective genomic tool to dissect complex asymptomatic carriage of vaccine preventable diseases. This has been built on the long-term, internationally recognised expertise in our group for microarray design, bioinformatics and pathogen genomics. Predominantly this current activity has focused on Streptococcus pneumoniae and the roll-out of pneumococcal vaccines, but parallel methods for Haemophilus influenzae and Group B Streptococcus have also been developed, the latter of which will see increasing demand in future as the first new vaccines undergo trials and potential roll-out. The pneumococcal molecular serotyping method developed in our group was shown to be the leading method for sensitive detection of multiple serotype carriage by the PneuCarriage project, a Bill and Melinda Gates Foundation funded methods evaluation. This has lead to adoption of the methodology in vaccine studies worldwide, analysing over 50,000 samples from studies in 25 countries, emphasising the international impact and success of this research.
Ongoing and future research activity aims to apply advances in metagenomics and sequence capture technologies to develop genomic approaches for direct analysis of clinical samples. Whilst the microarray approach has been highly effective in dissecting complex clinical samples following a culture-step, it has more limited sensitivity when analysing clinical samples directly. Targeted sequence capture methodologies upstream of next generation sequencing are a natural extension to the microarray approach, utilising similar principles and bioinformatics approaches to capture and analyse DNA of interest. Initially the primary aim is to enable sensitive direct analysis of challenging clinical samples from vaccine studies, for which current culture-based microarray approaches are not ideal. However, if shown to be an effective and a robust methodology, these sequence capture methods may supersede and improve upon current microarray approaches for all samples. A secondary important aim of this future research activity is to diversify the application of sequence capture beyond vaccine studies, for example, addressing wider issues such as the surveillance of respiratory viruses or circulation of antimicrobial resistance genes. These future plans build on our recognised expertise and productive collaborations with influential partners to maximise the potential impact and translational delivery through BUGS Bioscience.
