Dr Jenny Taylor is the Programme Director for the Genomic Medicine Theme, Wellcome Trust Centre for Human Genetics. Her research bridges the gap between genetics research and the use of its discoveries in diagnosis or treatment of medical conditions.

Cancer is a good example in which personalised medicine can help decide which molecular targeted therapy is most appropriate.
