Professional biography

Mr Aziz trained at St. Mary's Hospital Medical School where he obtained his MBBS degree in 2000. He undertook specialist colorectal training in the North-West London deanery programme and went on to complete a PhD at Imperial College London in 2008.

He secured the FRCS exam in 2011 and undertook a high volume laparoscopic (Ethicon) colorectal fellowship at St. Mark's Hospital (Harrow, London) in 2012, followed by a fellowship there in intestinal failure, inflammatory bowel disease surgery, inherited cancers and polyposis, recurrent cancer, restorative proctocolectomy, and coloproctology.

In 2014 Mr. Aziz joined The Christie, one of Europe's largest comprehensive cancer hospitals. At The Colorectal and Peritoneal Oncology Centre (CPOC), he specialises in complex minimally invasive (keyhole) and open surgical techniques to treat early, advanced, and recurrent tumours of the appendix, colon, rectum, and anus, including those that have spread to the lining of the abdomen (peritoneum), for which he performs cytoreductive surgery with hyperthermic intra-peritoneal chemotherapy (HIPEC). Over 150 such operations are carried out at The Christie's CPOC each year.

He is a member of the sarcoma team, the lead for endoscopy at The Christie, a national laparoscopic colorectal surgery trainer, and the consent lead for the trust.

Research Interest

Mr Aziz has developed evidence synthesis techniques to better guide healthcare decision-making and published over 100 peer-reviewed research papers, some of which have been used by institutions such as the UK National Institute of Clinical Excellence (NICE) in their guidance.

He was a member of the 2007 ‘Healthcare for London-A Framework for Action’ team reviewing the capital’s healthcare needs for the next decade.

He has an interest in translating biomedical research into new technologies for patient benefit and has obtained research grants from Innovate UK, Medical Research Council, Technology Strategy Board, and National Institute for Healthcare Research to this effect.
