Circadia

About us

We are an interdisciplinary group spanning the Department of Computer and Information Sciences and the Department of Psychology at Northumbria University. Our research focusses on the intersection of physics, computer science, physiology and chronobiology. We are particularly interested in sleep, rhythmicity, and medical signals of various modalities.

The word “Circadia” derives from the Latin “circa diem” meaning “around the day”, a reference to the circadian rhythms that govern our lives and the focus of our research. It also rhymes with “arcadia” - a place for exploration, discovery and learning.
