Karen received her BSc and Ph.D. in Genetics from Queen Mary College at the University of London working with Lorna Casselton, followed by postdoctoral fellowships with Chris Marshall at the Institute of Cancer Research in London and Douglas Lowy at the National Cancer Institute in the USA. She then became head of the Human Papillomavirus group the Ludwig Institute for Cancer Research in London before moving back to the NCI in 1995, where she was Director of the Molecular Virology and Carcinogenesis Section at the ABL-Basic Research programme and then Chief of the Regulation of Cell Growth Laboratory. In 2002 she returned to the UK to become the Director of the CRUK Beatson Institute in Glasgow, moving back to London in 2016 to take up the role of Chief Scientist at CRUK and Group Leader at the Francis Crick Institute.
Karen's research focuses on the tumour suppressor protein p53, which plays an important role in cancer prevention. Her lab is interested in understanding the signals that induce p53 and the functions of p53 that contribute to its ability to prevent cancer progression. This work has also expanded to encompass an interest in cancer metabolism. Ultimately, the hope is to be able find ways to translate this research for cancer therapy.
