Professor Engel is a specialist colorectal surgeon who trained in general surgery in the Netherlands and obtained his specialist colorectal training at the St Mark’s clinic in London, United Kingdom. On completing his PhD “Surgical and physiological aspect of faecal incontinence” in 1994 at the University of Amsterdam, he went on to chair a surgical training program for 10 years and supervised training of well over 30 young surgeons for over 20 years.

Prof Engel is a staff specialist at the Royal North Shore Hospital and North Shore Private Hospital and furthermore holds a teaching position at the University of Sydney. He is also a founding member of the European Society for Coloproctology and has served on many international scientific boards.

Professor Engel has been the centre director of ‘Sydney Vital,’ Translational Cancer Research Centre since 2013 and continuously supports the work that Sydney Vital is contributing to Translational Cancer Research.


Research Interests

His particular area of expertise is colorectal surgery in the elderly, para-stomal hernia, anorectal conditions, faecal incontinence, assessment and treatment of surgical complications and second opinions.
