Artificial Intelligence and Machine Learning for Enhanced Phenotyping of Breath Metabolomics Data
Exhaled breath contains a rich matrix of volatile chemicals (metabolites) that may be useful as disease biomarkers. However manual visual evaluation of metabolites from exhaled breath samples is subject to significant inter-expert and intra-expert variations. Furthermore conventional statistical techniques need to make prior assumptions on data models.
The PhD program will develop computer vision and deep learning (particularly convolutional neural network) techniques for the analysis and discovery of biomarkers from exhaled samples. Breath metabolomics data has already been acquired in approximately 600 patients with acute exacerbations of cardio respiratory disease in a large exhaled breath metabolomics program funded by the EPSRC/MRC. Breath samples have been acquired using GCxGC-MS and PTR-MS technologies in the acute state and during recovery from an exacerbation. The PhD will focus on biomarker discovery and replication within these existing rich datasets. The project will be hosted jointly in the Department of Computer Science, NIHR Biomedical Research Centre at Leicester University and East Midlands Breathomics Molecular Pathology Node. A range of training opportunities in artificial intelligence and data science will be made available to the successful candidate.
