Tammy Horton


My first degree is from Imperial College of Science, Technology and Medicine in London. It was during this time that I first gained an interest in deep-sea research by undertaking a final year project studying the 'Biological Implications of Deep-Ocean Waste Disposal'. I then went on to study for an MSc in Aquatic Resource Management at Kings College in London. As part of the MSc I worked at the MBA in Plymouth studying biofilm settlement cues for Ciona intestinalis and Balanus amphitrite amphitrite. After completing my MSc I worked for a year for the Environment Agency, first at their headquarters in Bristol, and then at the Fish Health Laboratories in Huntingdon. I then began my PhD in 1998 at the University of Reading studying cymothoid isopods. In November 2001, I completed my PhD thesis entitled ‘Genus Ceratothoa in wild and farmed fish: Taxonomy, Ecology and Pathology’ which was jointly supervised by Dr. Beth Okamura (University of Reading) and Dr.R.J. Lincoln (Natural History Museum, London). During my PhD I studied two cymothoid isopod parasites, Ceratothoa steindachneri and Ceratothoa oestroides.

Current Research Work:

I am currently working part-time on a £2 million UK project, ECOMAR (Ecosystems of the Mid-Atlantic Ridge) aimed at understanding how physical and biogeochemical factors influence the distributions and structure of deep-sea communities, focusing on the fauna of the Mid-Atlantic Ridge at 4 sites in different environmental settings. I have been employed as a researcher on a variety of deep-sea biodiversity projects at the National Oceanography Centre, Southampton, since 2001. Previous roles have included a 4-year BP-funded fellowship to study the taxonomy, biogeography and biodiversity of deep-sea amphipods, and a part-time post funded by the Esmee Fairburn Foundation on the 'Deep-Sea Conservation for the UK project'. As a young taxonomist I have a keen interest in the advances in modern methods of taxonomic databasing, interactive web-based keys (DELTA) and digital illustration that are currently taking place and I am making use of these tools in my research work.
