Human Biological Samples (HBS) sit at the heart of clinical research, enabling the discovery, development and delivery of new treatments and diagnostics. As ethically sensitive materials, they underpin every clinical trial and demand rigorous handling and oversight. The Senior Biobank Scientist maintains and develops the HBS inventory in line with Good Clinical Practice (GCP), global standards and standard operating procedures (SOPs), ensuring samples are received, logged, stored, tracked, despatched, returned and disposed of appropriately. Specialized IT systems and databases support compliant sample management, while daily interaction with stakeholders keeps studies moving at pace. This role brings deep expertise in microtomy and histology techniques such as staining and embedding to secure robust sample quality and reliable workflows, delivering a key regional tissue sectioning capability. It also helps build sectioning competencies and project readiness by providing experimental-ready samples to scientists, driving collaboration, capability creation and continuous improvement across processes and IT. In addition, the Senior Biobank Scientist may take on local Biobank Operations Manager responsibilities, coordinating local operations, leading user groups and providing local compliance knowledge, including national requirements. In the UK, this includes participation in an on-call rota under the Human Tissue Act (HTA) to safeguard the ongoing integrity of HBS.
