Past members

Sofia Mitrović

Sofia completed her Bsc in Biomedical Science with First class honours in 2023.

She is now starting to study for her BDS at the University of Sheffield

Alhassan Arafaie

Alhassan completed his PhD at School of Clinical Dentistry in 2023.

Raphael Peter Galleh 

Galleh completed his PhD at School of Clinical Dentistry in 2023.

PhD Research: “Understanding Glycans and Glycosidases in Infection and Biofilm formation as a Route to Novel Antimicrobials” under the supervision of Dr. Graham P. Stafford and Dr. Dan Lambert. My PhD is fully funded by Tertiary Education Trust Fund (TETFund) of Nigerian Government.

Ahmed Almuntashiri

Ahmed completed his PhD at School of Clinical Dentistry in 2022.

PhD project is involved in exploring the molecular microbiology of TonB-dependent transport of sialic acid and it’s role in oral bacterial physiology in the context of periodontitis. This is a key virulence trait that we aim to understand with a view to developing glycan based anti-microbials against periodontal pathogens. This project is supervised by Professor Graham Stafford and Dr Joey Shepherd.

Dr Liz completed her

Cher Farrugia

Cher completed her PhD at School of Clinical Dentistry in 2021.
