Mark O'Connell


MIBiol, CBiol (London), PhD (London)

As an Analyst at the ‘Poisons Unit’, Guy’s Hospital, London, from 1980 to 1986, Mark recognised the problems associated with diagnostics using conventional blood sampling. While studying for his PhD at the Institute of Neurology, London, he began using the then novel technique of brain microdialysis. As Principal Biochemist at the National Hospital for Neurology and Neurosurgery, London from 1991 to 1995, Mark pioneered the application of clinical microdialysis. In 1993 he began using intravenous microdialysis for drug monitoring in patients, publishing this ‘proof-of-principle’ work in the British Journal of Clinical Pharmacology. As Senior Clinical Scientist at Addenbrooke’s Hospital, University of Cambridge until 2005, his knowledge and expertise helped establish Cambridge as a leading centre in the field of microdialysis. Mark is an international speaker and author of over 50 scientific and medical papers.
