My research interests include investigation of the role of natural selection in population divergence, to which I apply a wide range of methods including multivariate morphometrics, statistical hypothesis-testing, innovative field experiments and DNA (both mitochondrial and nuclear) analysis. Knowledge of the phylogenetic history of organisms has recently gained an unprecedented importance in fields other than evolution (e.g. behaviour, ecology) as it has been recognised that all species operate within its constraints. I have two main lines of phylogenetic research on disparate organisms in different geographical regions (Anolis lizards in the Caribbean and Asian pit vipers), which are unified by being essentially focussed on the interface between evolution and ecology, and with an emphasis on the integration of genetic and phenetic data. More recently, my research has moved into the field of ecological and evolutionary genomics through development of collaborations to add other “omics” aspects to my genomic-focused research. This provides an opportunity to evaluate the evolution of genes affecting complex traits directly, e.g., toxin genes in Asian pitvipers. As well as relying on the availability of the organismal phylogeny, this grant drew on established collaborations to bring together disparate strands of organismal biology and ecology, evolutionary theory, comparative genomics, bioinformatics and proteomics to present an integrated picture of the evolution of snake venom components.
More recently, my research interests have widened to include other organisms apart from reptiles. For example, the recent interest in honeybee health, combined with personal involvement in beekeeping, has led me to co-ordinate a research program in collaboration with locally-based commercial and hobbyist beekeepers, to examine the main issues affecting honeybees in Wales. The honeybee is considered a “model organism”, and the availability of the entire genome sequence will allow more detailed analysis of the evolutionary dynamics of toxin genes than is currently possible in venomous snakes. In addition, the British/Welsh native black bee, a locally adapted race of Apis mellifera mellifera, is considered to be an endangered taxon and has recently been the focus of many initiatives to “recreate” its original characteristics. These mostly rely on questionable morphometric methods, and I am interested in providing genetic tools to assist these breeding projects. I have obtained the first genome sequence from a historical specimen of the UK native bee, and am currently seeking funding to develop this to investigate the historical decline of the native honeybee.

BITES (Bioinformatics and Information Technology to address Envenomation by Snakes): an International Research Staff Exchange Scheme funded by the EC (Dec 2013-2016).
India has the globally highest annual death rate from venomous snake bites and in some states it is the largest contributor to mortality, exceeding even AIDS and malaria. Clinical management of snake bites requires timely administration of antivenin, neutralizing the life-threatening toxins in snake venom. Snake venom composition varies both between and within species, and so the design and production of efficient antivenins depends on thorough understanding of venomous snake diversity and distribution. This four-year project addresses the lack of studies investigating the link between venomous snake systematics and regional venom variation in India, through collaboration between taxonomists, molecular biologists, protein biologists and herpetologists based in the EU (Drs Anita Malhotra, Wolfgang Wüster and John Mulley from Bangor University, Prof Juan Calvete from Spain and Dr Ulrich Kuch from Germany) and India (Drs BL Dhananjaya from Jain Universityand Kartik Shanker from the Indian Institute of Sciences, both in Bangalore, and Dr Robin Doley from Tezpur University, aAsam). The resulting biological information and standards will contribute to improving the outcome of snake envenomations and providing a baseline for future work.
