Peter Campbell is Head of Cancer Genetics and Genomics at the Wellcome Trust Sanger Institute and is joint head of the Cancer Genome Project. He is also a practising haematologist at Addenbrooke's Hospital in Cambridge.

His research programme focuses on the genetic changes our cells acquire as we go through life, and how these mutations are related to ageing, cancer and other disease processes. His major interest is in cancer genomics, and in particular genome-wide analyses of somatic mutations in tumours. Particular focus areas include how somatic mutations delineate clonal relationships of normal cellular populations and how somatic mutations affect normal cellular behaviour.
