Dr Jack Helliwell


I am an NIHR Academic Clinical Fellow in General Surgery at the University of Leeds. 

My interest in research was sparked as a second-year medical student at the University of Leeds when I was awarded the EXSEL scholarship. This allowed me to gain considerable laboratory-based experience alongside my undergraduate studies, which was supplemented by further research training at Yale University, USA. 

Upon graduation in 2018, I completed the Academic Foundation Programme and was awarded an NIHR Academic Clinical Fellowship to explore novel approaches to the prevention of anastomotic leak after colorectal cancer surgery.

Research interests

I am interested in the role of the gut microbiome in the development of anastomotic leak. I am specifically interested in bacterial collagenase production and how this may be modulated to improve anastomotic healing. 

I work within the Academic Surgery Colorectal Research Group and collaborate closely with colleagues in molecular pathology and medical microbiology.
