Dr. Róisín O’Flaherty earned her BSc in Chemistry at Maynooth University and a PhD in Glycochemistry at Maynooth University, Ireland.  She travelled to Australia to do a Research Fellowship in Glycochemistry at the Bio21 Institute, Melbourne University. She then worked as a Process Engineer in Intel in Leixlip, Ireland and subsequently joined the National Institute for Bioprocessing Research and Training (NIBRT) as a Senior Post-Doctoral Researcher utilizing her expertise in automation in the field of Glycoscience. She was appointed Research Manager in the Cell Technology Group at NIBRT before relocating to join Maynooth University as an Assistant Professor in the Department of Chemistry. She is responsible for the creation of some of the world’s most advanced automated glycoanalytical technologies. The developed technologies have found application in human health, with the recent establishment (and validation) of a clinical method for Classical Galactosemia in conjunction with the Mater Hospital and the characterization of complex biological matrices (e.g. blood serum, milk, and biopharmaceuticals (e.g. mAbs, erythropoiesis-stimulating agents) towards understanding complex glycan processing pathway alterations during disease states.
