Hazel's research profile is largely centred around health inequalities for adults with intellectual disabilities. Having completed her PhD in 2008 on the experience of health consultations for people with intellectual disabilities she published related papers in the British Journal of Learning Disabilities (BJLD) and Learning Disability Practice. As part of a Royal College of Nursing-sponsored study led by Prof. Kay Mafuba of the University of West London, she was involved in four studies exploring the role and impact of intellectual disabilities nurses, all published in the Journal of Intellectual Disabilities. Hazel edited the June 2024 special edition of the BJLD on health inequalities for people with intellectual disabilities. She is also undertaking research into quality improvement in the care needs of adults with intellectual disabilities and complex physical or communication needs. Using her psychology degree, Hazel has also had several papers published with her psychology research collaborator, Dr Claudine Clucas, into the experience of respect in student nurses and Registered Nurses. Hazel is a Chartered Member of the British Psychological Society and therefore often uses psychology theory to underpin her research.
