Biography

Since 2005 employed as a Marine Ecologist in the Ecosystems Programme at BAS

Previous appointments:

2002-2005 Post graduate research assistant, University of Aberdeen and FRS Marine Laboratory, Aberdeen . Collection and analysis of biological and fisheries data on cephalopod species, heavy metal analysis of cephalopod tissues and trophic ecology of deep-sea fish.

Post-school education:

2004 PhD Squid and their prey: insights from fatty acid and stable isotope analysis, University of Aberdeen
1999 MSc (Diplom) Zoology with Marine Biology and Oceanography, Christian-Albrecht-Universität, Kiel, Germany.

Research interests

My research focuses on marine food webs, their functioning and connectivity. I have mainly worked on the pelagic ecosystem but have also begun to study bentho-pelagic coupling in Antarctic and temperate shelf systems. To investigate trophic interactions in these communities I apply biochemical methods such as stable isotope and fatty acid analysis. Most recently I have used a novel suite of lipid biomarkers, highly branched isoprenoids (HBIs), in order to study the contribution of ice-algae to Antarctic marine food webs. I am also involved in studying the role of zooplankton in the carbon flux to deep water in the Southern Ocean.
