Question: Which fellow of one of the constituent colleges of the University of Oxford in England and the fourth oldest college of the University, is a Professor of physics at the University of Oxford?
Context: Keble College is one of the constituent colleges of the University of Oxford.  It was founded in memory of the Anglican clergyman John Keble, who died in 1866, and was intended to cater for men whose financial resources were insufficient to enable them to study at one of the older Oxford colleges.  After a public appeal for donations in John Keble's memory, the college opened in 1870.  The college's buildings – which were quite unlike any previous Oxford college, with their use of coloured bricks in patterns – were designed by William Butterfield; there have been later additions as the college has grown. St Anne's College is one of the constituent colleges of the University of Oxford in England.  Formerly a women's college, it has been coeducational since 1979.

Jesus College Boat Club (commonly abbreviated to JCBC) is a rowing club for members of Jesus College, Oxford, one of the constituent colleges of the University of Oxford.  The club was formed in 1835, but rowing at the college predates the club's foundation: a boat from the college was involved in the earliest recorded races between college crews at Oxford in 1815, when it competed against Brasenose College.  In the early years of rowing at Oxford, Jesus was one of the few colleges that participated in races.  Neither the men's nor the women's 1st VIIIs have earned the title of "Head of the River", which is gained by winning Eights Week—the main inter-college rowing competition at Oxford.
