I teach on the modules:

I also teach on field courses in the UK (Slapton) and abroad (Malaysia) as well as supervising undergraduate and postgraduate research projects
I am interested in the use of molecular tools to understand processes that maintain and erode genetic diversity in natural populations. I am also interested in the application of these tools to solve ecological problems of importance for conservation and management.
My previous research has involved assessing genetic diversity, gene-flow and population structure in declining populations of bumblebee species. I have also developed molecular tools to identify cryptic species of bumblebee and to identify wireworms (which are significant agricultural pests of potato). In addition to work on insects, I have also been involved in a large-scale research project to help understand the marine ecology of Atlantic salmon (the ‘SALSEA-Merge’ project).
More recently, I have become interested in the nature of the relationship between estimates of genetic diversity based on neutral markers and those based on functional regions: it is important to understand how adaptively important genetic variation is affected by the forces known to shape neutral genetic variation and the consequences for conservation. Recent work has focussed on identifying patterns of selection at potential candidate loci involved in immunity and metabolism in bumblebees within this context.
Current projects include: (1) Conservation genetics of the Hazel dormouse with Dr Ed Harris and Fraser Combe (MMU PhD student) (2) Population genetics of the colonization of the UK by Bombus hypnorum with Dr Mairi Knight (Plymouth University) 3. Adaptive conservation genomics of European Grayling with Dr Martin Taylor (UEA), Dr Robin Sen (MMU) and the Grayling Research Trust. (4) Ecological restoration of china clay mining sites with Dr Michael Hanley, Dr Mairi Knight and Dr Paul Lunt and Sibelco
The beauty of molecular tools is that they can be broadly applied across a wide range of taxa. If you have research interests on any group that you feel match my interests I am very happy to discuss potential PhD studentship applications, post-doctoral research or other collaborations
CURRENT & RECENT RESEARCH PROJECTS
Victoria Buswell & B4 'Bringing back black bees', NERC-CASE studentship:
With Mairi Knight (PI), Vanessa Huml and the B4 organisation, Victoria is investigating the phenotypic and genotypic basis of local adaptation in UK populations of the dark European honey bee, Apis mellifera mellifera. Collaborative work with Washington State University is planned on cryopreservation of honey bee sperm.
Vanessa Huml, PhD project:
Vanessa is funded by Manchester Metropolitan University (where I used to work) and the Grayling Research Trust, but is based in Plymouth. She is examining genetic diversity of MHC loci in European grayling (Thymallus thymallus) in relation to bacterial and environmental parameters as well as in contrast to neutral variation, using next-generation sequencing approaches (Ion Torrent). Collaborating on the project are Dr Ed Harris and Dr Robin Sen (MMU), Dr Martin Taylor (UEA), Richard Cove (Natural Resources Wales). Dr Steven Weiss is an external advisor.
Vanessa Huml & Kirsty Lloyd:
With P.I. Dr Mairi Knight (Plymouth University, DoS), Dr Mark Brown (Royal Holloway) and Prof Dave Goulson (Sussex) this project is examining the population genetics of the colonisation and subsequent expansion of Bombus hypnorum in the UK.
Mary Lane, PhD student:
Mary is working on the ecological restoration of heathland after china clay extraction. Her PhD is part-funded by Sibelco. Her work involves the investigation of the role of mycorrhizal fungi as well as metal nutrients. It involves laboratory work and field-scale trials
Fraser Combe, PhD student:
Fraser is studying for his PhD at Manchester Metropolitan under Dr Ed Harris (DoS). Fraser is examining landscape and conservation genetics of the hazel dormouse (Muscardinus avellanarius) in the UK. He works closely with a number of wildlife trusts, but particularly with Dr Simone Bullion at Suffolk Wildlife Trust.
Sarah recently completed her PhD with Dr Mairi Knight (Plymouth Unversity, DoS), Dr Richard Billington and Dr Mark Brown (Royal Holloway) examining genetic diversity and fitness (parasite load and immunocompetence) in Bombus monticola (in contrast to the closely related but widespread B. pratorum). Research outputs are in prep.

In my spare time I am a keen cyclist (roadie) and used to compete at an amateur level on the local scene as part of Team Certini. I now ride and race for Plymouth Corinthian CC. I also enjoy reading, especially Russian literature. I am attempting to learn Russian and Polish.
