How our team works

We strongly believe that our patients receive the best care when we work together as a team. The organisation of our clinical team reflects this. The team consists of doctors from a range of specialties, including surgeons, anaesthetists, oncologists, radiologists and pathologists, as well as nurses, dietitians, physiotherapists and administrative staff. The core team members are shown below.

Our approach means that our patients may be treated by any of the team members. Therefore, if you are a patient, you may see different doctors at different points in your journey. For example, you may see Mr Barham in clinic, and may have surgery under the care of Mr Titcomb. Organising our team this way allows us to make sure that we provide 24/7 specialist care, and helps us to share the workload within the team to minimise waiting times for treatment.


We can be contacted via our secretarial team on 0117 342 4007. 


Mr Paul Wilkerson

I studied medicine at St George's Hospital and undertook my surgical training in London. I have been a consultant upper GI surgeon in Bristol since 2015, specialising in minimally invasive and endoscopic treatments of oesophageal and gastric disease. As well as providing upper GI cancer care, I am working to improve care quality for Barrett's oesophagus (a condition that is linked with an increased risk of developing oesophageal cancer). I am the surgical lead for emergency laparotomy as part of a multidisciplinary team working to improve quality of care for high risk emergency surgery. I am also the Medical Information Officer for the Division of Surgery, and am driven to integrate digital change into how we deliver clinical care.


Ms Jenni Wheat

Having graduated in medicine from the University of Wales, College of Medicine and Cardiff University, I completed my specialist surgical training in Wales. During my training I completed an MD in the health economics of oesophageal and gastric cancer care through Cardiff University. After a few months as a locum upper GI consultant at the University Hospital of Wales in Cardiff, I undertook a fellowship at Addenbrookes Hospital Cambridge. Here I focussed on oesophageal and gastric cancer surgery, including minimally invasive oesophagectomy and endoscopic management of Barrett's oesophagus and early oesophagogastric cancer. 

In 2021 I was appointed as a consultant oesophagogastric surgeon at the Bristol Royal Infirmary, University Hospitals of Bristol and Weston, where my clinical practice includes general and emergency surgery, and specialist upper GI benign and cancer surgery.


Mr Dan Titcomb

I graduated in medicine from the University of Bristol and completed my specialist surgical training in the South West region. I was awarded an Association of Upper GI Surgeons travelling fellowship in 2009, to train in advanced minimally invasive upper GI cancer surgery at the Cancer Institute Hospital, Tokyo. I have also undertaken minimally invasive training courses in Versailles and Gothenburg. I was appointed as a Consultant Upper GI surgeon in Gloucestershire in 2009 before taking up my Consultant post in Bristol in 2010. I have a special interest in the management of dysplastic Barrett's oesophagus and helped establish the endoscopic service for this condition after my appointment. I also have a special interest in minimally invasive oesophagogastric cancer surgery and have been international faculty helping train colleagues to perform these surgical techniques in both the United Kingdom and Europe.


Mr Sean Strong

I graduated in medicine from the University of Southampton and undertook my specialist surgical training in the South West region. During my training I completed a PhD at the Centre for Surgical Research at the University of Bristol, which included a research fellowship award from the Royal College of Surgeons of England. My research interests have included maximising recruitment to trials in surgical oncology. After completing my specialist training, I undertook a fellowship at the Karolinska Institute in Stockholm. This focused on minimally-invasive and robotic techniques for the treatment of oesophago-gastric cancer.


Mr Ben Byrne

I graduated from Cambridge University in 2004, and undertook my clinical training in both the Wessex and Severn regions. I gained sub-specialist surgical training through a Royal College of Surgeons Oesophago-Gastric Cancer Fellowship at St Thomas' Hospital in London in 2019-20. Alongside my clinical training, I completed a PhD at Imperial College London, using mixed methods to study the performance of surgical units. I subsequently continued to conduct surgical research at the University of Bristol examining the relationship between clinical trials and usual practice. I started working as a consultant in Bristol in 2020. My research profile is available  here. I am also clinical governance lead for the GI and endoscopy service at the Bristol Royal Infirmary.


Dr Stratis Alexandridis

I finished my training in Gastroenterology medical specialty at the largest Cancer Insititute in Northern Greece focused on the treatment of gastrointestinal neoplasia and continued my training in interventional endoscopy in the Edinburgh Royal Infirmary. I pursued additional training in Endoscopic Ultrasound (EUS) in Amsterdam Medical Centre under the guidance of Professor Paul Fockens, previous UEG president and pioneer of interventional endoscopy. I also undertook further additional training in Endosocpic Submucosal Dissection (ESD) and magnifying endoscopy in Japan under the guidance of leading experts (Professors Toyonaga and N Uedo for ESD, and Professor Y Sano for magnifying endoscopy) in the University Hospital of Kobe and Osaka International Cancer Institute.

I have a special interest in diagnosis and surveillance of Barrett's oesophagus with magnifying endoscopy as well as interventional endoscopic treatment of early cancerous lesions of the upper GI tract. I am currently the endoscopy training lead in University Hospitals Bristol and Weston NHS Foundation Trust.
