Current Research

Colin Crooks has completed his PhD in the epidemiology of upper gastrointestinal bleeding studying its causes and outcomes using case control studies and survival analyses. This work was carried out in linked the routine databases; (CPRD) Clinical Practice Research Datalink, (ONS) Office for National Statistics, and (HES) Hospital Episode Statistics. After returning to full time clinical training as a gastroenterologist and NIHR recognised Academic Clinical Assistant Professor. He has now completed training and has been appointed as a Clinical Associate Professor in Gastroenterology in the NDDC. Code from his current work on developing statistical learning methods for routine health data is available online at https://github.com/ColinCrooks/
