Bio: Dr Lewis Blackburn completed his PhD at the University of Sheffield in 2021 within the Immobilisation Science Laboratory (ISL) and was further awarded the EPSRC Doctoral Prize Fellowship to develop advanced zirconolite and pyrochlore-structured ceramics for the immobilisation of separated actinides. Lewis was subsequently contracted by Nuclear Waste Services (NWS) to investigate the long-term evolution of candidate ceramic wasteforms for the immobilisation of separated Pu. His primary research interests involve synthesis, advanced characterisation, chemical durability and radiation stability of advanced ceramic and glass-ceramic materials for radioactive waste immobilisation. Lewis was promoted to Lecturer in Nuclear Materials in 2023.
