The Department of Pathology is one of the largest Departments in the School of Biological Sciences and seeks to understand – and so ultimately arrest and reverse – disease processes of medical and social significance. The work of the Department is organised into five Divisions: Cell and Molecular Pathology, Immunology, Microbiology and Parasitology, Virology and Molecular Histopathology, split between the University site and Addenbrooke's Hospital, as well as undertaking cross-disciplinary research with colleagues at Research Institutes including the Cambridge Institute for Medical Research and the Hutchison-MRC Institute for Cancer Research.

The Department of Pathology is not open to the public.
