We look forward to seeing you on Wednesday 14 October!

Imperial Inauguralsare term-time lectures that celebrate our newest Professors, recognising their academic journey and showcasing their research.

Abstract

Artificial intelligence is transforming medical imaging, promising more accurate diagnosis, earlier detection of disease, and better clinical decision-making. But the path from research prototype to trusted clinical tool remains difficult. AI systems can silently fail when new data differs from the data on which they were trained. Changes in patient populations, imaging protocols, and healthcare settings across geographic regions can cause distribution shifts that undermine the reliability, robustness, and fairness of AI predictions.

In this inaugural lecture, Professor Ben Glocker explores why causality matters for understanding when AI works and when it fails. He will discuss the role of ‘what-if’ reasoning and the use of the latest causal generative models to create realistic counterfactual images that can stress-test AI systems, expose blind spots, and mitigate bias. Ultimately, causality may be the missing ingredient that turns medical imaging AI from a promising technology into a life-saving reality. 

Biography

Ben Glocker is a Professor in Machine Learning for Imaging at Imperial’s Department of Computing where he co-leads the Biomedical Image Analysis Group. He holds a Royal Academy of Engineering Research Chair in Safe Deployment of Medical Imaging AI, and also leads the Heartflow-Imperial Research Lab. He received his PhD from TU Munich, was a postdoc at Microsoft and a Research Fellow at the University of Cambridge. His research is at the intersection of medical imaging and artificial intelligence, aiming to build safe and ethical computational tools for improving image-based detection and diagnosis of disease.
