Illustration of a sleeping figure connected to a polysomnography signal panel (EEG, EOG, EMG, ECG, respiration, SpO2), which resolves into detected sleep events and a night-long hypnogram, then into interpretable biomarkers of arousal, breathing, movement, and stability that feed sleep-age, fragmentation, and neurological-risk insights.

Sleep carries a dense, non-invasively recorded signal of physiological and neurological health. This theme develops interpretable, deep-learning-based markers of sleep health, aging, fragmentation, and neurological disease directly from polysomnography and related physiological recordings, organized around two complementary strands of work: detecting the individual clinical events that make up a sleep study, and characterizing what a whole night — or a whole cohort — of those events says about a person’s health.

The first strand, automated sleep event detection, builds the scoring systems a sleep study depends on — the events a technologist would otherwise annotate by hand. The second, whole-night biomarkers and phenotyping, moves past individual events toward summary measures of a full recording, from a single “sleep age” estimate to a foundation model trained across very large clinical cohorts.

Automated sleep event detection

Development and validation of deep-learning methods for automated detection of core polysomnographic events, including cortical arousals, leg movements, and sleep-disordered breathing events.

Whole-night sleep biomarkers and phenotyping

Move beyond individual events toward whole-recording and probabilistic descriptions of sleep physiology, including sleep age, fragmentation, and disease-related signatures.
