Stephen Andrew Bustin (born 1954), PhD, FSB is a British scientist, former professor of molecular sciences at Queen Mary University of London from 2004 to 2012, as well as visiting professor at Middlesex University, beginning in 2006. In 2012 he was appointed Professor of Allied Health and Medicine at Anglia Ruskin University. He is known for his research into polymerase chain reaction, and has written a book on the topic, entitled A-Z of Quantitative PCR. This book has been called "the bible of qPCR." After giving testimony about the unreliability of a study that had reported using PCR to detect measles virus RNA in autistic children in the autism omnibus trial, he developed the MIQE guidelines in a 2009 paper published in Clinical Chemistry, the goal of which is to create guidelines for how PCR should be performed to ensure that PCR results are being reliably conducted and interpreted, as well as to make replication of experiments easier. This paper is the fifth most cited one ever to be published in Clinical Chemistry, with over 1700 cites on Google Scholar as of September 2013.
