Dr Chris Creevey M.Sc. Ph.D.
Dr Creevey completed a double honours degree in Computer Science and Biology in 1997 and a research masters in Ecology in 1999. In 2002 he received his PhD from the National University of Ireland for his work in the area of phylogenetics and comparative microbial genomics. Following this he worked as a postdoctoral researcher for the McInerney Lab in NUI Maynooth developing methods of resconstructing phylogenetic supertrees and detecting horizontal gene transfer (HGT) in genomic data. In 2005 he took up a postdoctoral position in the Euorpean Molecular Biology Laboratory (EMBL) in Heidelberg, Germany where the focus of his research involved the reconstruction of the tree of life, and the use of metagenomic and expressed sequence tag (EST) data for the phylogenetic analysis of unculturable organisms or for those we have no genomic information. In 2009 Dr. Creevey was awarded a Science Foundation Ireland Stokes Lecturership, at Teagasc, (The Irish agriculture and food development authority) in Ireland where his group worked on identifying the genomic factors influencing phenotypic changes in organisms from Bacteria to Eukaryotes, and the development of novel approaches to investigating metagenomic data from rumen microbial communities. He started his current position in IBERs in 2013.

Dr. Creevey is currently the Theme Director of Research for Animal and Aquatic Sciences in IBERS. He is also part of the Herbivore Gut Ecosystems group where he lab specialises in using computational approaches to understanding the ecology and evolution of microbial ecosystemsMy research interests include:
- Developing novel computational approaches to understanding the complex interaction of the host-associated microbiomes.
- Understanding the effect of host-associated microbial community structure on the efficiency and health of the host
- Metagenomic and metatranscriptomic analysis of microbial communities.
- Application of graph (phylogenetic and network) techniques to metagenomic and metatranscriptomic samples.
- Analysis of whole genomes of microbial organisms.
- Development of novel approaches for phylogenomic and evolutionary analyses.
