My research involves the application of mass spectrometry to health and disease. I have a particular focus on human milk profiling and developing methods to take a systems biology approach to understanding the role that different components of human milk play in the development of the infant microbiome. My work takes a combination of approaches employing 'omic technologies with culture-based microbiology.

As a microbiologist by training, I maintain a wider interest in the application of mass spectrometry (focusing on ambient ionisation mass spectrometry) to microbial applications including in animal and plant disease diagnosis, and understanding microbe-microbe and host-microbiome interactions.
