Kay Davies

field = Genetics Joan Mott Prize Lecture (2010) Croonian Lecture (2018) spouse = a director of the Oxford Centre for Gene Function, and a patron and Senior Member of Oxford University Scientific Society. Her research group has an international reputation for work on Duchenne muscular dystrophy (DMD). In the 1980s, she developed a test which allowed for the screening of foetuses whose mothers have a high risk of carrying DMD.

Early life and education Davies was born in Stourbridge, Worcestershire (now West Midlands). She was educated at the Gig Mill School, Stourbridge County High School for Girls, Somerville College, Oxford, and Wolfson College, Oxford. She was awarded a Doctor of Philosophy degree in 1976 for research on the structure and function of chromatin from the slime mould Physarum polycephalum.

Career and research Davies's research group has an international reputation for work on Duchenne muscular dystrophy (DMD). In the 1980s, she developed a test which allowed for the screening of foetuses whose mothers have a high risk of carrying DMD. DMD occurs when the dystrophin protein fails to express in muscle cells due to a mutation in the gene which codes for the protein. In 1989 Davies discovered that the utrophin protein has similar properties to dystrophin and has since shown in mouse models that up regulation of the former protein in muscle cells can compensate for the absence of latter.

Davies is currently collaborating with European Research Council fellow Dr Peter Oliver investigating neurodegenerative and movement disorders.

Davies is director of the Medical Research Council (MRC) functional genetics unit, a governor of the Wellcome Trust and, with Frances Ashcroft and Peter Donnelly is a director of the Oxford Centre for Gene Function. She was an Executive Editor of the journal Human Molecular Genetics. and stepped down in 2021.

In 2020, together with Richard P. Lifton, she co-chaired a commission report on the contentious subject of Hereditary Human Genome Editing, under the auspices of the National Academies of Sciences, Engineering, and Medicine and the UK Royal Society.

She has published more than 400 papers and won numerous awards for her work. She has been a Governor of the Wellcome Trust since 2008 and became Deputy chairman in 2013-18. She was the recipient of the Women in Science and Engineering (WISE) Lifetime Achievement Award in 2014.

Her former doctoral students include Irene Miguel-Aliaga The paper however came under scrutiny at the end of 2023, and was ultimately retracted in 2025 due to issues regarding the ethical approvals and subject recruitment of the study not adhering to the standards.

She is an Honorary Fellow, Somerville College, University of Oxford. She gave the inaugural Rose Lecture at Kingston University in 2012 and delivered the Harveian Oration at the Royal College of Physicians in 2013. In 2015, she was awarded the William Allan Award by the American Society of Human Genetics. She was appointed a Patron of The SMA Trust in September 2016.

Davies was awarded the Croonian Lecture by the Royal Society in 2018 for "her achievements in developing a prenatal test for Duchenne muscular dystrophy and for her work characterising the binding partners of the protein dystrophin".

Personal life Davies continued to work with her former husband, Stephen G. Davies, on scientific projects, even after their separation in 2000.
