John Greenlees obtained his PhD from Cambridge in 1986, and spent 3 years at the National University of Singapore and a year at the University of Chicago before moving to Sheffield in 1990. He spent 28 years there, serving as Head of Pure Maths and then Head of the School of Mathematics and Statistics before moving to Warwick as Head of Department in 2018. He has published over 90 papers and 4 books on algebra and topology, and serves on the editorial boards of 3 algebraic topology journals. He has acted as undergraduate External Examiner for 5 institutions, and conducted external reviews for 7 departments.

John was an organizer of the Oberwolfach Homotopy Theory meetings between 2007 and 2015, a meeting on the Kervaire Invariant at the ICMS in 2011, a 4 month programme at the Isaac Newton Institute in 2002 and the 6 month programme Homotopy Harnessing Higher structures in 2018. He was on the Scientific Committee of the ICMS 2011-20, and has been on the INI Management Committee since 2020.

John was Vice President of the London Mathematical Sciences from 2009 to 2019, and a member of the Board of the Council for Mathematical Sciences. He is Deputy Chair of the REF2021 Mathematical Sciences Subpanel, and also served on subpanels in REF2014 and RAE2008.
