Head of Unit:
Professor Richard Tedder
Tel: 020 8327 6109 / 6553


Richard Tedder has a joint appointment with PHE, the NHS Blood and Transplant Service (NHSBT) and UCL. The Blood Borne Virus Unit is engaged in research and development on Hepatitis Viruses and works closely with the Seromolecular Services Unit (SSU) and the NHSBT.

Some of the work of the PHE Blood Borne Virus Unit is around improving blood safety. This is funded by NHSBT and members of the unit work closely with colleagues in the NHSBT/PHE Epidemiology Unit.
