Introduction to Dr Johns

Dr Johns began his working life as a geologist, specializing in hydrogeology. However, he went back to University and studied medicine. After postgraduate clinical training in Internal Medicine at Alfred Hospital, Melbourne, he went on to do a PhD in sleep medicine. He was the first person in Australia to do so, at a time when the discipline of sleep medicine did not exist. He did full-time sleep research in Australia, USA and UK for eight years. However, he was unable to practice sleep medicine until he set and ran the Epworth Sleep Centre, Melbourne, in 1988. His was the first private sleep laboratory and practice of sleep medicine in Australia.  He retired from clinical practice in 2002, by which time the Epworth Sleep Centre was well known for its clinical practice and research, nationally and internationally.

Dr Johns has a special interest and expertise in the state of drowsiness or sleepiness, and how it can be measured. He became acutely aware of the dangers associated with that state for people whose very lives depend on them remaining awake at the appropriate times, eg when driving. In 1994 he began to develop new technology for monitoring the drowsiness of drivers continuously. He called that technology Optalert ™. Dr Johns was the founding Director and Chief Scientist of a company that was set up specifically to develop and commercialize that technology. That Company is now called Optalert Pty Ltd.

Dr Johns has another personal website www.epworthsleepinessscale.com which deals only with the Epworth Sleepiness Scale which he developed in 1990.

Dr Johns is also associated with a corporate website www.optalert.com dealing  with Optalert technology for monitoring drowsiness continuously in active people, such as drivers of cars, trucks, trains, etc. Dr Johns is the Founding Director and Chief Scientist of Optalert Pty Ltd.

The Epworth Sleep Centre has its own website
