Consultant transplant surgeon


Nikolaos Karydis received his undergraduate medical education and general surgical training at the University of Athens, Greece. Before completing his training, he was awarded a PhD in experimental liver injury from the same university.

Early in his career, he was fascinated by solid organ transplantation. He moved to the UK to train further in liver and pancreatic surgery as well as in multi-organ abdominal transplantation in Newcastle upon Tyne. Following this, he completed his sub-specialty training in kidney and pancreas transplantation at Guy’s Hospital in London.

He also teaches medical students on a regular basis (honorary senior lecturer, King’s College London). More recently, he has taken on the role of joint training programme director for transplant surgery trainees (London Deanery).
