My research interests focus on the role of natural selection in population adaptation and divergence, to which I apply a wide range of methods including multivariate morphometrics, statistical hypothesis-testing, innovative field experiments and genome analysis. I have two main areas of 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 to evaluate the evolution of genes affecting complex traits directly and relies on the availability of a well-supported and complete organismal phylogeny of Asian pitvipers generated by my students and myself. Drawing on numerous collaborations to bring together disparate strands of organismal biology and ecology, evolutionary theory, comparative genomics, bioinformatics and proteomics, I aim to develop an integrated picture of the evolution of snake venom components. Another strand to this research on venomous snakes involves snakebite mitigation, and I am currently involved in several projects in India on this topic.
I am also involved in research on the genetic health of honeybees, sparked off by personal involvement in beekeeping. I am also involved in projects on the genetic identification of British/Welsh native black bee, a locally adapted race of Apis mellifera mellifera, and an endangered taxon which is the focus of many initiatives to “recreate” its original characteristics. However, identification of “near-native” stocks mostly rely on morphometric methods, which may not be accurate enough for this purpose after many generations of admisxture with other subspecies and requires verification using molecular methods. With the aid of a genome sequence from a historical specimen of native bee developed during a period of study leave, a cost-effective tool for rapidly assaying the amount of native genomic contribution present in current stocks is part of a PhD studentship funded by the Drapers’ Trust (with Dr Paul Cross).

The BITES Project (Bioinformatics and Information Technology to address Envenomation by Snakes):
Snakebite was described as “the biggest public health crisis you have likely never heard of” by Kofi Annan, shortly before his death. The World Health Assembly recently adopted a landmark resolution calling for immediate and effective steps to address the snakebite crisis, following the addition of snakebite to their influential list of neglected tropical diseases (NTDs) in 2017. India has the largest estimated annual mortality from snakebite, with c. 50,000 deaths, and likely even more permanent disability caused by the bite among survivors. Both reduction in incidence of snakebite and reduction in mortality will have a significant economic and humanitarian impact.
Resolving the taxonomy of venomous snakes is acknowledged as a key component in the development of a strategy for the improvement of the snakebite situation by the Global Snakebite Initiative. Most of the venomous snake species that occur in India, especially in the northeast, have at least part of their ranges, or close relatives, outside the political boundaries of India and include species for which the Bangor group have established world-leading expertise.
We began a collaborative EU-funded project in 2013 with a number of Indian institutions, with the aim of improving antivenom formulation through identifying the mixture of clinically relevant species present in different regions, and evaluating the effectiveness of the current antivenom towards the venom of snakes from different regions. Although the original fundin has come to an end, we are continuing the project with various other sources of support.
