Steve received a degree in Genetics from Edinburgh and a PhD from Cambridge, followed by post-doctoral positions and a lectureship at Stirling before moving to Liverpool in 2003. His research focuses on genetic diversity and evolution in host-parasite interactions using clinical, laboratory and veterinary models. He helped pioneer the evolve and resequence approach to experimental evolution and has worked widely in RNAseq, population genomics, microbiomes and epigenetics. During the pandemic he helped develop methods to sequence SARS-CoV2 variants from wastewater and led a consortium of laboratories delivering genomic surveillence to UK health agencies. He is a director of the Centre for Genomic Research, director of the Natural Environment Omics Facility (NEOF), which provides expert advice, capability and training to the environmental sciences community. He established the Microbiome Innovation Centre, which provides a focus for academic and industry-facing microbiome research. He is able to offer PhD projects in the area of infectious disease, microbiomes, genomics and evolution.
