Amanda Fisher

Dame Amanda Gay Fisher is a British cell biologist, Whitley Professor of Biochemistry at the University of Oxford and former Director of the Medical Research Council (MRC) London Institute of Medical Sciences at the Hammersmith Hospital campus of Imperial College London, where she was also Head of Department at the Institute of Clinical Sciences. She has made contributions to multiple areas of cell biology, including determining the function of several genes in HIV and describing the importance of a gene's location within the cell nucleus.

As a postdoctoral researcher, she produced the first functional copies of HIV, providing researchers with access to enough biologically active material to study the function of the virus's genes. She later became interested in epigenetics and nuclear reprogramming, particularly in white blood cells known as lymphocytes and embryonic stem cells. As of 2016 her research focuses on how gene expression patterns are inherited when cells divide, using lymphocytes as a model system.
