Redox pioneer: Professor Barry Halliwell

Professor Barry Halliwell is recognized as a Redox Pioneer because he has published eight articles on redox biology that have been each cited more than 1000 times, and 158 articles that have been each cited more than 100 times. His contributions go back as far as 1976, when he was involved in elucidation of the Foyer-Halliwell-Asada cycle, an efficient mechanism for preventing oxidative damage to chloroplasts. His subsequent work established the important role of iron and zinc in free radical reactions and their relevance to human pathologies. Professor Halliwell is also a leader in developing novel methodology for detecting free radical intermediates in vivo, and his contributions to our knowledge of reactive nitrogen species are highly significant. His sustained excellence won him the top-cited scientist award in the United Kingdom in biomedical sciences in 1999, and in 2003 he was recognized as a highly cited scientist by Institute of Scientific Information (ISI) for work on plant antioxidants, and the same year ranked 28 out of 5494 biochemists/biologists for scientific impact. Two pieces of his scholarly work have been listed as Citation Classics by ISI, and in 2007 his laboratory was ranked number 1 worldwide based on highest citation score in research on free radicals
