Stephen Fox is an internationally recognised anatomical and molecular pathologist. He is known for his research in the field of tumour blood vessel formation where he elucidated the mechanism by which a tumour establishes a blood supply that is critical to its growth and spread. He has shown the importance of these in breast tumours and its effect on patient response to treatment. He has developed and implemented novel molecular cancer testing from research to diagnostic laboratories and written several Australian guidelines that has changed the way laboratories test for genetic changes in cancer.
