Mike Goldsmith has a PhD in astrophysics from Keele University, awarded for research into variable supergiant stars and cosmic dust formation. From 1987 until 2007 he worked in the Acoustics Group at the UK's National Physical Laboratory and was Head of the group for many years. His work there included research into automatic speech recognition, human speech patterns, environmental noise, and novel microphones. He continues to work with NPL on a freelance basis and has recently lead a three-year project to develop a new type of environmental noise mapping system. He has published over 40 scientific papers and technical reports, and since 1999, he has written over 30 science books for readers from babies to adults. Two of his books have been short-listed for the Aventis prize (now the Royal Society prize) for science books.
