John has a PhD in evolutionary genetics and now lectures in Sheffield. I obtained a Genetics degree at Manchester before working as a postgraduate research assistant in Cambridge for a few years. I then moved to Edinburgh to study evolutionary genetics of a wild red deer population and was awarded my PhD in 2000. I next moved to New Zealand on a Royal Society fellowship, before returning to the UK in 2002. I am now a lecturer at the University of Sheffield. My research interests are centred around evolutionary and population genetics and now involve a fairly broad range of taxa. This article was published on 2024-06-17
