Scientific interests

• Lipids as indicators of organic matter origin in sediments
• Lipids as trophic indicators
• Reconstruction of sea surface temperature using alkenones

Previous work

• Using lipids as indicators of organic matter origin around a fish farm in the Gulf of Eilat, Israel
• Using sedimentary lipids to consider differences in organic matter flux to 4 stations of similar depth (about 1400m) on a transect between the Norwegian and Svalbard margins
• Using sedimentary lipids to consider differences in organic matter supply along a latitudinal transect from Svalbard west into deep water (2500m)
• Using lipids to distinguish differences of location, depth and diet in the cold water coral, Lophelia pertusa
• Influence of diet on the lipid composition of 2 species of sea urchin (Paracentrotus lividus and Psammechinus miliaris)
• Using lipids to distinguish differences of location and diet in the caprellid, Caprella mutica
• Influence of diet on the lipid composition of 2 species of sea urchin larvae (Paracentrotus lividus and Psammechinus miliaris)
• Influence of diet on the lipid composition of the abalone, Haliotis tuberculata
