Mark is an Upper Gastrointestinal and Bariatric surgeon with a special interest in the management of obesity, gastro-oesophageal conditions, and cancers of the stomach and oesophagus.

Originally from London, Mark graduated from the Imperial College School of Medicine before moving to New Zealand, where he completed his General Surgical training and became a Fellow of the Royal Australasian College of Surgeons (FRACS) in 2013. He first came to Dunedin as a medical student and quickly developed a deep connection with the region and its people.

Following his FRACS qualification, Mark undertook subspecialty post-fellowship training in the United Kingdom. He completed an Oesophagogastric Fellowship at University Hospital Southampton, gaining extensive experience in managing complex benign and malignant conditions of the oesophagus and stomach. He later served as a Consultant Oesophagogastric Surgeon at both University Hospital Southampton and Queen Alexandra Hospital in Portsmouth.

Mark returned to New Zealand in 2017 to complete dedicated Bariatric Surgery training at Waitematā DHB, where he performed both primary and revisional bariatric procedures. He is now appointed as an Upper Gastrointestinal and Bariatric Surgeon at Te Whatu Ora Southern.

Academic Qualifications
Master of Medical Science (MMedSci)
Title of Thesis: Anatomical and physiological characterisation of a novel porcine model for varicose veins
Postgraduate research degree involving laboratory-based translational surgical research. The thesis developed and validated a large-animal (porcine) model of chronic venous disease, examining venous anatomy, valve competence, haemodynamics, and vein wall remodelling under conditions of sustained venous hypertension. The work demonstrated that varicose veins represent a combined disorder of venous valve failure and intrinsic vein wall pathology, providing a platform for further investigation into surgical and endovascular interventions.
