The Department of Informatics delivers the highest quality undergraduate and postgraduate programmes in computer science through the commitment and enthusiasm of its staff within a stimulating, research-led context.

In the 2014 Research Excellence Framework (REF), Informatics at King's was rated as having 92% of its research outputs as world leading or internationally excellent. The 2014 REF results placed the Department in the top 10 of Computer Science and Informatics departments in the UK, when measured by the Power Ranking.

The Department is organised into research groups focusing on algorithms and data analysis, cybersecurity, distributed artificial intelligence, human centred computing, reasoning and planning, and software systems.

Cross-cutting hubs in health, security, urban living and finance provide a virtual clustering of researchers from all parts of the Department, with the fifth hub (autonomous systems) providing a technology focus for the Department as a whole. The Department also leads the UKRI Centre for Doctoral Training in Safe and Trusted Artificial Intelligence, which is training a new generation of researchers in model-based AI approaches and their use in ensuring the safety and trustworthiness of AI systems.
