James O. McInerney

James McInerney at the School of Life Sciences, University of Nottingham.

James O. McInerney is an Irish-born microbiologist, computational evolutionary biologist, professor, and former head of the School of Life Sciences at the University of Nottingham. He is an elected Fellow of the European Academy of Microbiology, of the American Society for Microbiology, and of the Linnean Society. In June 2020 he was elected president-designate of the Society for Molecular Biology and Evolution and in 2022 he took up the role of President. He is deputy chair of BBSRC committee C.

Early life and education McInerney completed his bachelor's degree at NUI Galway. In 1994, he was awarded a PhD (also from NUI Galway). In August 2024, McInerney moved to The University of Liverpool to take up the position of Head of the Department of Evolution, Ecology and Behaviour.

McInerney's early research career focused on the study of codon usage in a variety of organisms including Trichomonas vaginalis and Borrelia burgdorferi. McInerney was the first to show that the leading strands of replication and the lagging strands of replication in a prokaryotic genome could have significantly different codon usage patterns, due to the way in which polymerases replicate DNA. One of his first software packages, GCUA, allowed for the accessible and reproducible analysis of codon usage by other biologists. Since then, the McInerney research group has published several bioinformatic software programs including Clann: Software for inferring phylogenetic supertrees, Crann: Software for inferring selection, Modelgenerator: Amino acid and nucleotide substitution model selection, PutGaps: DNA gapped file from amino acid alignment, and TIGER: Identifying rapidly-evolving characters in evolutionary data.

Currently, the McInerney lab focusses on understanding the origins of eukaryotes, and on understanding horizontal gene transfer, and prokaryotic pangenomes and the assemblage of genes within them

McInerney has been funded by the Biotechnology and Biological Sciences Research Council (BBSRC), Leverhulme Trust, The European Molecular Biology Organisation, and Science Foundation Ireland and with start-up funding from both the University of Manchester and the University of Nottingham.
