Few, if any, genes have had the same level of impact on the field of evolutionary-developmental biology (evo-devo) as the Hox genes. These genes are renowned for their roles in patterning the body plans and development of the animal kingdom.

Dr David E.K. Ferrier leads the Evolutionary Developmental Genomics (EDGe) group in the Scottish Oceans Institute, in the School of Biology at the University of St Andrews (UK). Dr Ferrier's research is focused on the interplay between genome organisation and content with the evolution of animal development. Much of his research has been concentrated on the homeobox-encoding genes, such as the Hox genes, and he has published papers on these genes in species from across a wide range of the animal kingdom.
