Dr Tracey Mitchell joined King's and Guy’s and St Thomas’ Hospital in 2000. She holds a King's adjunct senior lecturer position and leads the Viapath Skin Tumour Unit Molecular Diagnostic Laboratory in St John’s Institute of Dermatology. Her laboratory provides a molecular diagnostic service to detect clonal T- and B-cell antigen receptor gene rearrangements, for the diagnosis and clinical management of cutaneous lymphomas. Translational research is also fundamental to the laboratory and current research projects include functional analysis of gene mutations detected in cutaneous T-cell lymphoma, affecting T-cell signalling pathways and the DNA damage response. Tracey is an academic Lead on the MRC Doctoral Training Partnership in Biomedical Sciences.
