Dr Valerie O’Donnell is Professor of Biochemistry and Co-Director of the Systems Immunity Research Institute, Cardiff University. She uses mass spectrometry to uncover new lipids involved in inflammatory processes, and is funded by British Heart Foundation and Welcome Trust. She is an ERC Advanced Investigator. Following a PhD in Bristol, studying enzymology of NADPH oxidase in neutrophils, she completed post doctoral fellowships in Bern, Switzerland and with Bruce Freeman and Victor Darley-Usmar at University of Alabama at Birmingham. She moved to Cardiff in 1999 on a Wellcome Trust CDA Fellowship. Her research group studies vascular inflammation, applying informatics, machine learning and statistics to global analysis and discovery lipidomics projects which aim to uncover new mechanisms of lipid signaling in disease.
