Mark Lawrence is married with four children, one of whom is severely disabled. Before becoming a fulltime writer in 2015 day job was 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'. Mark used to have a list of hobbies back when he did science by day. Now his time is really just divided between writing and caring for his disabled daughter. There are occasional forays into computer games too.
