As a clinical pathologist and tumour biologist, Gareth Thomas’s research is focused how fibroblasts affect cancer progression, characterising the phenotypes and functions of different fibroblast subpopulations and investigating how fibroblasts interact with immune cells to suppress anti-tumour immunity. The research has a strong translational component aiming to develop new therapies that target fibroblasts to overcome immunotherapy resistance. Adopting a multi-disciplinary approach, his research group interacts widely with other members of Cancer Sciences, the Faculty of Medicine, the University, and colleagues in academia and industry, both nationally and internationally.

Professor Thomas’s team is investigating the role of cancer-associated fibroblasts in tumours; characterising phenotype and function, with a focus on interactions with immune cells and mechanisms by which CAF promote tumours immune escape and promote resistance to immunotherapy. The aim of the lab is to develop novel therapies that target CAF to overcome immunotherapy resistance, and the group collaborates widely with industry partners to deliver this. A major focus of the group is head and neck cancer, with clinical studies overseen by Professor Emma King (consultant Head & Neck Surgeon).
The research group typically comprises 3-4 Postdoctoral Fellows, 1 research technician, 2-4 PhD students and 3 medical laboratory scientists.

Gareth Thomas graduated from University of Wales College of Medicine (UWCM) in 1989 with a degree in Dentistry. He gained his FDSRCS (Eng) in 1994 and undertook an MScD at UWCM (awarded 1995). He was subsequently awarded an MRC Clinical Training Fellowship to undertake a PhD in keratinocyte biology at University College London (awarded 2000) and completed his clinical training in Head & Neck pathology at University College Hospital London in 2004 (MRCPath 2004, FRCPath 2008). Following the award of a Health Foundation/Royal College of Pathologists Clinician Scientist Fellowship in 2004, he combined research at Bart’s Cancer Institute with clinical practice as a Consultant Pathologist at University College Hospital. In 2007 he was appointed Chair of Oral & Maxillofacial Pathology at Bart’s and the London, and moved to Southampton as Professor of Experimental Pathology in 2009.

Chief Investigator Investigation of the molecular and genetic mechanisms promoting head and neck cancer development and progression, UKCRN 8130; ISRCTN 71276356. This currently the largest current UK study in Head & neck Cancer (>1300 patients recruited). This has resulted in some of the largest UK biomarker studies in this disease (Marsh et al., 2011; Ward et al., 2014) with findings incorporated into recent pathology reporting guidelines for oropharyngeal and oral cancer published by the Royal College of Pathologists. Research from the study has resulted in multiple high impact publications (including Nature, Nature Immunology, Nature Communications, Cancer Research, Clinical Cancer Research, Journal of Clinical Oncology).
