Benthic Ecologist

A marine zoologist specialising in the ecology of benthic invertebrates. Research experience covers a wide range of habitats extending from coastal waters to the deep-sea bed, and from the Arctic to the tropics.

Contact details:

My research career began with work on the ecology and life history of bryozoans in UK coastal waters. This led to work on the bryozoan communities of Caribbean coral reefs during a postdoctoral fellowship at the Smithsonian Tropical Research Institute in Panama. At SAMS I have carried out extensive diving fieldwork in Scottish sea lochs, including in situ measurements of bioturbation by large burrowing invertebrates and the growth rates of reef-building serpulid tubeworms. From 1998 onwards I have been involved in deep-sea biology at SAMS, participating in research cruises to the north-east Atlantic, the Arctic Ocean and the western tropical Pacific. Deep-sea research has included studies of habitat and community zonation across the continental slope west of Scotland, the effects of large burrows on radiotracer profiles in seabed sediments, and the ecological impacts of large-scale disposal of mining waste in Papua New Guinea.

I am also the Year 2 Leader on our Marine Science BSc (Hons) programme.

Consultancy and industry experience

I have over 30 years research experience in a wide range of marine environments around the world. Work has ranged from assessing the environmental impact of anthropogenic activities (such as offshore development, waste disposal and climate change) on deep-sea ecosystems to the ecology and conservation of rare benthic communities in Scottish waters. I am an experienced provider of contract research reports and literature reviews concerned with survey and data analysis for marine biotopes of conservation importance, ranging from the coastal zone to the deep-sea west of Scotland. I also have considerable experience in identification and enumeration of flora and fauna from benthic samples and video/still photographs.

I am a very experienced scientific diver (>1000 logged dives) and am also comfortable working from ocean-going vessels. Over the last 20 years I have participated in research cruises to the north-east Atlantic, Arctic Ocean and tropical Pacific, including the 2007 and 2008 SAMS surveys in Papua New Guinea.
