Contact Details


I obtained my Ph.D from the University of Bristol in 2002 based on studies in Professor Keith Edwards' laboratory on the use of transposon-tagging to identify genes involved in grain development of maize and wheat. I subsequently undertook two postdoctoral research projects at Bristol on the consequences of hybrid speciation and polyploidy in Senecio (ragworts) with Professor Simon Hiscock. In addition to my scientific interests, I am a keen amateur photographer.



I run the IBERS Translational Genomics facility, which provides next-generation DNA sequencing and high-throughput genotyping to the whole of IBERS (and collaborators). As such, my primary role is driving the adoption and use of these technologies for a range of projects in both plant, animal and microbial systems. I am also in charge of overseeing the research themes of the Genomic Diversity Group at Aberystwyth, which requires me to conduct research in a number of areas related to genetic diversity (particularly the use of natural diversity in improving plant breeding programmes) and conservation genetics in both plant and animal systems (see the GDG webpage for more information).
