Research interests + projects

We apply some of the most sophisticated analytical tools available to determine the applications and limits of ‘omics, particularly breath analysis and transcriptomics, working with collaborators from around the world. In our basic science work, we are keen to understand the origins and consequences of the volatile molecules we find in breath and the transcripts in blood. A particular focus is on respiratory infections – viral, bacterial, and fungal – however, we are also interested other human and animal diseases. Our work over the past several years shows great promise, particularly for bacterial infections.
