== Education == Micklefield attended Royds Comprehensive School in Leeds. He received his BSc. Degree in Chemistry from Hull University in 1989 and earned a Ph.D. from the University of Cambridge in 1993 working with Professor Sir Alan Battersby to complete the first total synthesis of haem d1, a coenzyme in bacteria.
== Career and research == Following his PhD, Micklefield was awarded a NATO fellowship to work on enzyme mechanisms and biosynthesis with Professor Heinz G. Floss at the University of Washington, Seattle USA. In 1995, Micklefield was appointed Lecturer in Organic Chemistry at Birkbeck College, University of London, before moving to Manchester in 1998. He was promoted to Professor of Chemical Biology at the University of Manchester in 2008 where his research group is based in the Manchester Institute of Biotechnology (MIB). Micklefield is also visiting professor at the East China University of Science and Technology (ECUST) in Shanghai. He is co-director of the EPSRC Centre for Doctoral Training in Integrated Catalysis (iCAT) and served as Director of the BBSRC Natural Product Discovery and Bioengineering Network (NPRONET). Micklefield was the recipient of the RSC Interdisciplinary Prize (2022), Bader Award (2019), [https://pubs.rsc.org/en/content/articlehtml/2009/np/b819603f Natural Product Reports (NPR) Lecture Award (2008]). He also received a [https://erc.europa.eu/news-events/news/erc-2023-advanced-grants-results European Research Council (ERC) Advanced grant] and his lab also won the [https://www.rsc.org/prizes-funding/prizes/2023-winners/enzyme-discovery/ RSC Horizon Prize & Rita and John Cornforth Award (2023)].
