Philip is a PhD student in the Volatile Biomarker Group within the Division of Surgery, under the primary supervision of Professor George Hanna.

The overarching aim of his research is to investigate the link between volatile organic compounds (VOCs) and lipid reprogramming in the tumour microenvironment to uncover novel therapeutic targets in gastrointestinal cancers. These VOC biomarkers can then be translated clinically with a non-invasive breath screening test to identify patients at early disease stages and improve outcomes. 

Philip was recognised with the Departmental Staff Award in Education (2022) for excellence in teaching and student support, and the College Union Award for outstanding graduate teaching assistant (2023).
