Projects per year
I developed an early interest in algae and ecophysiology whilst studying for my BSc in Botany at the University of Liverpool and subsequently stayed on there to do a PhD on a non-heterocystous cyanobacterium that fixes nitrogen aerobically. I then moved to Bristol University for a 2-year UK Natural Environment Research Council (NERC) Postdoctoral Fellowship focussing on chemotaxis in cyanobacteria, before moving to the University of East Anglia (UEA) for 8 months to work on biogenic production of dimethylsulphide (DMS). After this I worked at Case Western Reserve University, Ohio, USA on high-affinity arabinose uptake in E. coli; a project that I undertook to learn more biochemical and molecular techniques.
I returned to UEA and DMS-related research in March 1987 and over the following 10 years I developed a portfolio of research projects on production of DMS, halocarbons and hydrocarbons, and air-sea gas exchange. Most of these involved phytoplankton and seaweed physiology and marine microbial ecology. In 1998 I won a 5-year NERC Advanced Fellowship to work on the biogenic production of trace gases of atmospheric significance in marine waters. In 2004 I was awarded a rare second 5-year NERC Advanced Research Fellowship to develop physiological and molecular approaches to biogenic trace gas production. During these Fellowships I established a research group and the Marine Trace Gas Biology Laboratory in the School of Environmental Sciences (ENV). Since my appointment to a Readership in Biological Oceanography in 2009, I have continued research in these areas alongside my teaching and administration.
From 2002-2009 I was Chair of the ENV Researchers' Affairs Forum and represented Research Staff on the ENV Executive Group, the UEA Research Staff Working Group and UEA Research Staff Training Steering Committee. After joining the ENV faculty I was the ENV Health and Safety Co-Ordinator and Chair of the ENV Health and Safety Committee for 4 years (2009-2013). I am currently involved in action on gender equality and fairness through Chairing ResNet (www.uea.ac.uk/resnet) a contact, support and information network for people working in research, teaching and support roles at the University of East Anglia and the Norwich Biosciences Institutes. I am also a member of the UEA Athena Swan Central Steering Group and the ENV Equality and Diversity Committee. Beyond UEA I am President Elect for the British Phycological Society and a member of the Phycological Society of America Grants and Awards Committee. My interests in the sustainable production and exploitation of seaweeds and microalgae are reflected in chairing the British Phycological Society Algal Applications Committee and being an active participant in the NERC and Technology Strategy Board Algal Bioenergy Special Interest Group.

Key Research Interests and Expertise
The biogenic production of the sulphur trace gas dimethyl sulphide (DMS), volatile halocarbons and non-methane hydrocarbons are of particular interest. In addition my group works on the DMS precursor dimethylsulphoniopropionate (DMSP), and we have also investigated related compounds including dimethylsulphoxide (DMSO), acrylic acid and inorganic iodine species. The research involves laboratory experiments on samples collected in the natural environment and cultures of marine microorganisms (phytoplankton, microzooplankton, seaweeds, bacteria and viruses), and fieldwork onboard research ships, on rocky shores, at land-based coastal fieldwork sites and mesocosm facilities. Overall our research has made a significant contribution to improving understanding of the physiology, biochemistry and ecology of the production of trace gases and related compounds.
These interests have also led me to research on other aspects of biological oceanography, biogeochemistry and the exploitation of algal biomass. Recent projects have included: oxidative stress in Emiliania huxleyi; phytoplankton cell death processes; ocean acidification; using flow cytometry to assess the size structure of North Sea phytoplankton populations; the variability in DMSP production between and within phytoplankton functional types (coccolithophores, dinoflagellates and diatoms); nutrient and sulphur deficiency and DMSP production in Emiliania huxleyi and Thalassiosira pseudonana; the production of trace gases by temperate and tropical seaweeds; diatom, coccolithophore and nanophytoplankton growth rates and carbon cycle modelling; the sustainable exploitation of algae for biofuels and other high-value products.
MSc, PhD & Postdoctoral Research Opportunities to date I have supervised 23 PhD students and 1 MSc student (11 as primary supervisor). I welcome enquiries from potential students and postdocs at any time.
