Paul Senior became Professor of Probation Studies in 1996 following a career in probation from 1977 to 1994, which included 11 years as a joint appointment between South Yorkshire Probation and Sheffield Hallam University. He was co-editor of the three-volume, fifth edition, of Jarvis from 1992. As a freelance consultant, Paul's extensive engagement in probation training secured, in 1997, a key role in its revision, creating the structure and curriculum for the new, graduate level, Diploma in Probation Studies. In 2002, having developed a robust criminology and community justice presence within Sheffield Hallam University, Paul started the Hallam Centre for Community Justice, a contract research centre specialising in offender management, resettlement and restorative justice, where he is now Director. Paul launched the Community Justice Portal (http://www.cjp.org.uk) providing an online information exchange facility in 2002, which also saw the creation of the international journal, the British Journal of Community Justice in a partnership between Hallam and de Montfort universities, which he continues to co-edit. Paul's career has thus been linked to policy, practice and research in and around probation and with probation partners in criminal justice. He has written on many aspects of probation practice and community justice and two recent books include Understanding Modernisation in Criminal Justice (2007) with Crowther-Dowey and Long and Moments in Probation (2008). His association of 38 years with probation has seen Paul engaged as a practitioner, manager, trainer, consultant, researcher, advisor and policy developer in the UK and in Europe, Hong Kong and Singapore.
