David Burnell was born and bred in York. He studied mathematics at Cambridge University and then taught the subject in northern Ghana in West Africa. There he came across Operational Research, a practical branch of mathematics with relevance to a developing country. In his holidays he took students to support Wycliffe Bible Translators in remote villages. On returning to the UK he completed an MSc in the subject at Lancaster University.
In his professional career he tackled management problems in the Health Service, coal mining and latterly the water industry. Over 20 years he and his team completed many projects, including a daily scheduling system for the many pumps on the new London Tunnel Ring Main, smarter ways of managing water treatment and an in-depth study of pipe leakage. His team won an Innovation Award from the British Computer Society and a Presidents' Medal from the Operational Research Society.
On "retiring" he completed a PhD at Lancaster University on the deeper meaning of data from London's water meters.
He and his wife live in Berkshire but they own a small holiday cottage at Tintagel in North Cornwall. They have four grown-up children and five grandchildren.
When not on the Cornish Coast Path or the Thames Path, David is hard at work on the next "Cornish Conundrum"; or on writing more short stories of "Peril and Predicament".
