Mark Lawrence is married with four children, one of whom is severely disabled. His day job is as a research scientist focused on various rather intractable problems in the field of artificial intelligence. He has held secret level clearance with both US and UK governments. At one point he was qualified to say 'this isn't rocket science ... oh wait, it actually is'.
Between work and caring for his disabled child, Mark spends his time writing, playing computer games, tending an allotment, brewing beer, and avoiding DIY.
