Early life and education
Foot was born on 23 February 1961 and is the daughter of the military historian M. R. D. Foot and his second wife Elizabeth. She was educated until 1979 at Withington Girls' School in Manchester. She then went up to Newnham College, Cambridge, to study at the Department of Anglo-Saxon, Norse, and Celtic, where she was taught by, amongst others, Rosamond McKitterick and Simon Keynes, completing that tripos in 1983. She graduated with a Bachelor of Arts (BA) degree in 1984; as per tradition, her BA was promoted to a Master of Arts (MA Cantab). She was awarded her Doctor of Philosophy (PhD) degree in 1990: her doctoral thesis, written under the supervision of Rosamond McKitterick, was titled Anglo-Saxon Minsters, AD 597 – ca. 900.

Academic career
Foot was, from 1989 to 1990, research fellow at Gonville and Caius College, Cambridge, before becoming a fellow and tutor there. In 1993 she took up a lectureship at the University of Sheffield, being promoted to senior lecturer in 2001. In 2004, she was appointed to the newly established chair of Early Medieval History.

On 22 February 2007 Queen Elizabeth II appointed Foot to the Regius Chair of Ecclesiastical History at the University of Oxford. She is the first woman ever to hold this chair. Postholders are expected to lead research and develop graduate studies within their areas of specialisation and to take a leading part in developing the work of the Oxford theology faculty. The professorship is also annexed to a canonry at Christ Church, although the post-holder need only be a layperson; and at a special ceremony on 6 October 2007 Foot was installed as residentiary canon of the cathedral.

In March 2023, Foot's appointment as the Dean of Christ Church was approved by King Charles III. She is the first woman to serve in the role. She took up the appointment effective 1 July 2023, and was installed at the cathedral during a service on 8 July. The dean is both head of an Oxford college (Christ Church) and of the cathedral of the Diocese of Oxford (Christ Church Cathedral).

Among her current projects are the charters of Bury St Edmunds Abbey. She contributed to an episode of BBC Radio 4's In Our Time on the life of St Cuthbert, broadcast in January 2021. is an editor of the Oxford History of Historical Writing.
