Dr Paul Keedwell studied Medicine and Psychology at Leeds University and is a member of the Royal College of Psychiatrists. He has a PhD on the neuroscience of mood disorder, with a keen interest in how evolution has shaped our emotions. He has written widely on many aspects of psychology and mental health, also appearing on national radio and television. His more artistic side has been drawn to architecture and design, which he studied part time at London Metropolitan University. This led to a dissertation on the psychological history of architecture. He has conducted a survey on emotional attachments to the home and contributed to the Channel Four TV series, The Secret Life of Buildings.
