Role
I am programme leader for the Marine Biology and Oceanography degree course at Plymouth University http://www1.plymouth.ac.uk/courses/undergraduate/2055/Pages/CourseOverview.aspx. I am also an active academic researcher working on various topics related to conservation and sustainable management of the deep sea and High Seas http://www1.plymouth.ac.uk/research/mberc/Research/Marine%20resource%20management/Pages/Deep-sea.aspx, and marine habitat mapping  http://www1.plymouth.ac.uk/research/mberc/Research/Marine%20resource%20management/Pages/Habitat-mapping.aspx  

Roles on external bodies
Member of the ICES Working Group on Deep-water Ecology (WGDEC)

Member of the United Nations General Assembly Pool of Experts of the Regular Process to help in the production of World Ocean Assessment I – the first integrated global assessment of the state of the marine environment, including socio-economic aspects.
 



Research interests

My primary research interests are in the field of deep-sea ecology, conservation and sustainable management. I have expertise in the design of high seas / deep-sea marine protected area networks, habitat classification, habitat mapping, predictive species modelling, population connectivity, deep-sea food webs and ecosystem impacts of deep-water fisheries. See our group website www.deepseacru.org for more details.

Marine habitat mapping is a critical part of moving toward our sustainable use of the marine environment. The European Commission recognises habitat mapping as providing new opportunities for blue growth and jobs in seas and oceans, and has proposed the creation of a digital seabed map of European waters by 2020 (see http://ec.europa.eu/commission_2010-2014/damanaki/headlines/press-releases/2012/08/20120829-1_en.htm). Our research will contribute to these efforts through: 1) developing novel techniques for mapping benthic biology at both broad and fine scales, 2) working with our European partners to develop the EUNIS habitat classification system such that it can adequately represent deep-sea biodiversity.

Current Projects
Mapping the Deep
The 'Mapping the deep' project will tackle the principle cause of destruction of the UK's cold water coral reefs, coral gardens and other vulnerable habitats (that is destruction caused by contact with bottom trawl gear), by providing maps of their distribution in order that appropriate protection measures such as the creation of marine protected areas, can be taken. These habitat maps will be created using predictive modelling approaches coupled with traditional habitat mapping methods. For more information on this project see:

Influence of population connectivity on depth-dependent diversity of deep-sea marine benthic biota.
Knowledge of how populations are connected is central to our understanding of population persistence, isolation, divergence, speciation and radiation. The bathyal region has been identified as the primary site of adaptive radiation in the deep-sea from molecular and morphological studies and is also where the peak in species diversity occurs in many ocean basins. Gene-flow is low over the depth gradient suggesting limited larval exchange occurs in the vertical. Recent research has suggested that larval dispersal potential may vary with depth. This variation, given the limited vertical exchange, may provide a mechanism for population isolation, divergence and speciation in the bathyal region. This study will adopt a multidisciplinary approach to investigate connectivity among deep-sea populations at different depths and spatial scales using: 1) larval dispersal modelling using Lagrangian particle tracking, driven by hydrographic models 2) population genetics/genomics and 3) benthic community analysis, using examples of sessile (scleractinian corals) and limited mobility (echinoid) species as test subjects. We will examine changes in larval dispersal, gene-flow, gene expression and community and taxonomic patterns with depth to identify possible variation in population connectivity down the vertical gradient. We will also examine patterns of connectivity at different spatial scales. Critically we will investigate whether the changes in connectivity from the shelf break to bathyal depths are correlated to current flow as predicted by hydrodynamic models and whether this physical mechanism significantly contributes to current patterns of diversity, potentially driving speciation at large spatial scales or, alternatively, whether other factors are influencing genetic structure.
