From pioneering digital recording to developing novel metrics of sleep & wake, these projects reflect a career shaped by curiosity, clinical rigor, and a genuine desire to move the field forward.
Each project represents a distinct chapter in sleep medicine. Select one to learn more.
An original invention — z-ratio provides a continuous, second-by-second quantitative measure of the sleep/wake continuum, going beyond traditional hypnogram staging to capture the full texture of a night's sleep.
View Project → Clinical InnovationAt Winthrop University Hospital (now NYU-Winthrop), Albertario led the transition to fully digital polysomnography — earning the first AASM accreditation for a paperless sleep laboratory in the world.
View Project → Professional AdvocacyCo-founded in 1998 alongside fellow practitioners, NYSSM became the vehicle through which polysomnography was codified into New York State law — a landmark for sleep technologists and patients alike.
View Project → Program DevelopmentLed the development and launch of the Weill Cornell Medicine & NewYork-Presbyterian Pediatric Sleep Center — bringing subspecialty-level diagnostic sleep care to children across the New York metropolitan region.
View Project → Standards & ScoringServed on the American Academy of Sleep Medicine Scoring Manual Committee for version 2.5 — contributing to the evidence-based standards that govern how sleep and its disorders are identified and reported.
View Project → Education & OutreachA long record of invited presentations at major sleep medicine conferences — covering polysomnography technique, digital recording methods, pediatric sleep, and the science of z-ratio.
