Q:Information: - Professor (commonly abbreviated as "prof.") is an academic rank at universities and other post-secondary education and research institutions in most countries. Literally, "professor" derives from Latin as a "person who professes" being usually an expert in arts or sciences, a teacher of the highest rank. - The University of Oxford (informally Oxford University or simply Oxford) is a collegiate research university located in Oxford, England, United Kingdom. While having no known date of foundation, there is evidence of teaching as far back as 1096, making it the oldest university in the English-speaking world and the world's second-oldest university in continuous operation. It grew rapidly from 1167 when Henry II banned English students from attending the University of Paris. After disputes between students and Oxford townsfolk in 1209, some academics fled northeast to Cambridge where they established what became the University of Cambridge. The two "ancient universities" are frequently jointly referred to as "Oxbridge". - Christ Church (the temple or house, "ds", of Christ, and thus sometimes known as "The House") is a constituent college of the University of Oxford in England. The college is associated with Christ Church Cathedral, Oxford, which serves as the college chapel and whose dean is "ex officio" the college head. - Christopher Brendan Reginald Pelling was the Regius Professor of Greek , at Christ Church , Oxford , from 2003 to 2015 . He is President of the Hellenic Society and is a representative for the Society at the Institute of Classical Studies Advisory Council . His research interests range over Greek and Latin historiography and biography , and also over other areas of Greek literature , especially tragedy . Biography is in fashion : one has only to scan the shelves in W. H. Smith 's to see that . And we all know what biographies and autobiographies are , do n't we ? They start at the beginning : so many autobiographies open with those depressing words '' I was born ... '' . -- Christopher Pelling , inaugural lecture , 20 May 2004 - The University of Dublin, corporately designated the Chancellor, Doctors and Masters of the University of Dublin, is a university located in Dublin, Ireland. It was founded in 1592 when Queen Elizabeth I issued a charter for Trinity College, as "the mother of a university", thereby making it Ireland's oldest operating university. It was modelled after the collegiate universities of Oxford and of Cambridge, but unlike these only one college was established; as such, the designations "Trinity College" and "University of Dublin" are usually synonymous for practical purposes. - Christ Church Cathedral is the cathedral of the diocese of Oxford, which consists of the counties of Oxford, Buckinghamshire and Berkshire. It is also the chapel of Christ Church at the University of Oxford. This dual role as cathedral and college chapel is unique in the Church of England. - A Regius professor is a university professor with royal patronage or appointment. They are a unique feature of academia in the British Isles. The first Regius professorship was in the field of medicine, and founded by the Scottish King James IV at Aberdeen University in 1497. Regius chairs have since been instituted in various universities, in disciplines judged to be fundamental and for which there is a continuing and significant need. Each was established by a British monarch, and following proper advertisement and interview through the offices of the university and the national government, the current monarch still appoints the professor (except for those at the University of Dublin in Ireland, which left the United Kingdom in 1922). This royal imprimatur, and the relative rarity of these professorships, means a Regius chair is prestigious and highly sought-after. Given the paragraphs above, decide what entity has the relation 'employer' with 'university of oxford'.
