His clinical interests have covered a wide range of cancer treatments and tumour sites including leukaemia, lymphoma, myeloma, melanoma, sarcoma and, most recently, urological cancers and cancers of teenagers and young adults. With Cliff Bailey and Ian Lewis from paediatric oncology he set up the Teenage and Young Adult Service in Leeds and he continued to practice within the team as much as possible until 2017. The team, now led by Dan Stark and Sue Morgan, was UK Cancer Team of the Year in 2013. His research programmes have been broad but always focused on research with the potential to benefit patients and included high dose chemotherapy with bone marrow/stem cell transplants, antiviral treatments, antiemetics, combination chemotherapies, biological therapies, biomarkers, psychosocial oncology and psychometrics, clinical trials and health service innovations.
