Experience

Dr Oguejiofor's current role as a clinical oncologist at University Hospital Southampton focuses on urological and head and neck cancers. He previously held senior registrar and fellowship positions at leading UK cancer centres, including:

Proton Beam Therapy clinical fellow, The Christie Hospital, Manchester
Specialist registrar in clinical oncology, Wessex and Portsmouth rotations
Core medical training, Southampton General Hospital
Medical Officer, Nigerian Air Force Hospital, Abuja.

His training reflects broad exposure to advanced radiotherapy techniques, systemic therapy, and multidisciplinary cancer management.

Research

Dr Oguejiofor’s academic career is anchored in translational radiobiology and tumour immunology, with a focus on HPV-associated oropharyngeal cancers. His PhD work at the University of Manchester explored immune microenvironmental differences in HPV-positive and negative head and neck cancers, contributing significantly to the understanding of immune–tumour interactions.

He has co-authored over 15 peer-reviewed publications in high-impact journals such as Clinical Oncology, British Journal of Cancer, and Oncotarget, covering topics including:

HPV-related tumour biology and diagnostics
Tumour-infiltrating lymphocytes and immunophenotyping
PD-1/PD-L1 pathway and tumour hypoxia in cancer prognosis
