David Kerrigan has worked with technology for over 20 years. He has a degree in Communications Studies and has worked with leading technologies companies such as Ericsson, Microsoft, IBM and Three across Ireland, the UK, France and Sweden

He began researching and writing Your Phone Can Save Your Life in 2014 having seen how technology has evolved in recent years to provide incredible advances but aware of the challenge posed by the speed of development - such is the pace of change that it's all to easy to miss out on what is now readily available and literally life-changing.

David has focused on providing a clear guide to the kinds of technology now available and the medical basis for using it, all in an accessible style with lots of practical advice.

Tremendous amount of material but essentially accessible and readable. Interesting and worthwhile, I came away with a great deal of new knowledge.
