Marcus de Guingand is the managing director of Third Pillar of Health, home of the sleep health self-assessment as well as the Alert-Risk, Shift-Risk and MyAlertness, apps.

Marcus recently completed two major studies of fatigue in those who drive for work and in construction workers across HS2. Across those two studies we gathered over 137,000 data points, from 795 workers and c. 6,000 separate working days using the custom-built Shift-Risk app.

Using this rich real-world data set Marcus worked with leading sleep scientists, circadian biologists, mathematicians and statisticians to develop a brand new biomathematical model of fatigue, which will finally provide industry with a tool that can effectively measure and manage fatigue risk by turning it from an invisible threat to a set of clear, actionable KPIs.
