Ai Sleep Science

Sleep Science Foundations

Doctoral work examines the biology and behaviour of sleep across the lifespan. Sleep occupies roughly a third of life and remains incompletely understood.

Sleep Architecture Research

Research examines how sleep stages are organised across a whole night. Architecture describes the structure that summary measures entirely conceal.

Sleep Stage Research

Doctoral study examines the distinct states through which sleep progresses. Stage definitions are conventions that shape all subsequent measurement.

Rapid Eye Movement Sleep

Research examines the active brain state accompanied by muscle paralysis. This state features vivid dreaming and distinctive physiological signatures.

Slow Wave Sleep Research

Doctoral work examines the deepest sleep marked by large synchronised waves. This state is most strongly associated with restorative processes.

Sleep Onset Research

Research examines the transition from wakefulness into fully established sleep. Onset is gradual rather than the switch that measurement implies.

Sleep Continuity Research

Doctoral study examines whether sleep proceeds without frequent interruption. Fragmentation impairs restoration even when total duration appears adequate.

Arousal Research

Research examines brief shifts toward wakefulness during established sleep. Arousals disrupt sleep continuity without producing any recalled waking.

Microarousal Research

Doctoral work examines very brief arousals detectable only in recordings. These events accumulate and measurably impair daytime functioning.

Sleep Depth Research

Research examines how strongly a sleeper resists being woken by stimuli. Depth varies continuously rather than following the discrete stages.

Sleep Spindle Research

Doctoral study examines brief rhythmic bursts characteristic of lighter sleep. Spindle activity relates to memory processing and to individual difference.

Slow Oscillation Research

Research examines very slow rhythms coordinating activity during deep sleep. These rhythms organise the timing of other sleep related events.

Cortical Dynamics Research

Doctoral work examines brain surface activity patterns throughout sleep. Cortical dynamics reveal processes that stage scoring entirely obscures.

Local Sleep Research

Research examines brain regions sleeping while others remain awake. Local sleep challenges the assumption that sleep is a whole brain state.

Sleep Homeostasis Research

Doctoral study examines sleep need accumulating during extended wakefulness. Homeostatic pressure explains why sleep deepens after prolonged waking.

Sleep Pressure Research

Research examines the mounting drive toward sleep during continued wakefulness. Pressure measurement supports understanding of individual sleep need.

Two Process Model Research

Doctoral work examines the framework combining homeostatic and circadian influences. This model remains the organising theory of sleep regulation.

Circadian Rhythm Research

Research examines internal daily rhythms governing physiology and behaviour. Circadian timing shapes sleep, metabolism and cognitive performance.

Central Clock Research

Doctoral study examines the brain region coordinating body wide daily rhythms. This region synchronises clocks distributed throughout the body.

Molecular Clock Research

Research examines the feedback loops generating rhythms within individual cells. Molecular rhythms operate in nearly every tissue of the body.

Clock Gene Research

Doctoral work examines genes whose activity generates daily biological rhythms. Variation in these genes influences individual sleep timing preference.

Peripheral Clock Research

Research examines biological rhythms operating within organs beyond the brain. Peripheral clocks respond to feeding as well as to light signals.

Light Entrainment Research

Scoring Reliability Research

Doctoral study examines agreement between people scoring the same recording. Human agreement sets a ceiling on measurable automated performance.

Home Sleep Testing

Research examines simplified recording conducted in a person own bedroom. Home testing improves access and captures fewer physiological signals.

Portable Monitoring Research

Doctoral work examines compact devices recording sleep outside laboratories. Portability widens access and reduces the signals actually available.

Actigraphy Research

Multimodal Sensing Research

Doctoral work examines combining several signal types together to assess sleep. Combination yields accuracy that no single signal achieves alone.

Signal Processing Research

Research examines mathematical treatment of recorded physiological signals. Processing choices strongly affect the measures eventually reported.

Artefact Handling Research

Doctoral study examines identifying and managing corrupted signal segments. Artefacts are pervasive and are frequently mistaken for real events.

Feature Extraction Research

Research examines deriving informative measures from the raw recorded signals. Feature choice determines what any analysis can possibly detect.

Spectral Analysis Research

Doctoral work examines frequency content of brain activity during sleep. Spectral measures capture gradation that stage scoring entirely discards.

Sleep Big Data Research

Doctoral study examines very large datasets gathered from consumer devices. Scale permits questions that laboratory studies could never address.

Digital Phenotyping Research

Light Exposure Research

Research examines light in the environment influencing sleep and rhythms. Evening light exposure delays internal timing really quite measurably.

Technology Use Research

Doctoral work examines device use before bed and its relationship with sleep. Content and timing may matter more than the light being emitted.

Social Determinant Research

Population Sleep Research

Research examines sleep patterns measured across whole national populations. Population data reveals trends that clinical samples cannot show.

Public Health Research

Doctoral work examines sleep as a population health concern and target. Sleep receives far less attention than diet and physical activity do.

Sleep Service Research

Research examines how sleep clinical services are organised and delivered. Service capacity falls far short of the recognised population need.

Economic Evaluation Research

Doctoral study examines value delivered by sleep treatments and services. Untreated sleep disorder carries substantial economic consequences.

Implementation And Adoption
