Director of Hull Health Trials Unit

Role at Hull York Medical School

Judith is the Director of the Hull Health Trials Unit (Hull HTU), which has been established in collaboration with the University of Hull and Hull and East Yorkshire NHS Trust. Hull HTU aims to collaborate with clinicians and academics from the region on locally-led, high-quality, multi-centre research. Judith joined the University of Hull/Hull York Medical School in November 2017 and is in the process of setting up the unit, which should be operational by summer 2018.


Judith previously worked at the University of Sheffield as Assistant Director of the Clinical Trials Research Unit (CTRU), and as an advisor for the NIHR Research Design Service Yorkshire and the Humber (RDSYH).  Judith obtained a BSc in Medical Biochemistry from the University of Leicester, and a PhD in the biochemistry of wound healing from the University of Sheffield. She completed early post-doctoral work at the University of Manchester, before moving into clinical research as a research project manager at the Wolfson Molecular Imaging Centre (trials involving translational imaging techniques including PET scanning and MRI). She joined Sheffield CTRU in 2007, and developed expertise in clinical trials methodology, including the design and implementation of large scale randomised controlled trials (RCTs) and she is co-applicant on active grants from the NIHR HTA, PHR and PGfAR.
