Dr Kirwan started her career as a clinical veterinarian where she became increasingly interested in how clinical research translated into changes in clinical practice and evidence based medicine. After completing her PhD at the University of Liverpool, she moved to the University of Birmingham, UK and from there to the Max Delbrück Center of Molecular Medicine, Germany. She is part of the Berlin Institute of Health (BIH) Initiative to improve translational research and now heads the BIH Metabolomics Platform in Berlin. This has enabled her to focus on health related metabolomics and mass spectrometry research and she is particularly interested in the gut-brain-heart health triad. She is currently involved in several studies which involve long term sampling and monitoring of individuals and this has led to an interest in appropriate biobanking of samples for metabolomics and lipidomics. She is also a member of the Metabolomics quality assurance and quality control consortium (MQACC) and the Evidence based veterinary network.
