My main research aim is to develop new analytical methodologies, which can be used to explore lipid metabolism in greater detail within commercially important aquaculture species, such as Salmon. Such methodologies are required to establish the parity between traditional feed formulations and those of novel feed ingredients, such as insects and GM oils, which may allow for more sustainable aquaculture. My work has included establishing a lipidomics platform for understanding the isomeric alterations that occur within Salmon, which have been fed feed containing novel terrestrial sources of omega-3.
My research interests generally focus around lipids, however I also develop methods for more targeted analysis, such as phytochemicals and compounds commonly utilised within the aquaculture industry. Common techniques include LC-MS/MS (Triple quad and QTof), HPLC and GC-MS. I also develop commercial methods for both food and human blood spot analysis, which has included Vitamin D and 25-OH Vitamin D from seafood and consumer blood spot testing kits.
