After the first "Nature" article on the x-ray diffraction results leading to the double helix model, he and Franklin (who had by that time left King's College) followed up their DNA x-ray analysis with a second article in "Nature". His other King's colleagues included Alex Stokes and Herbert Wilson. Gosling briefly remained at King's College following the completion of his thesis in 1954, but the 1953 work on DNA structure was not, at the time, viewed with the importance it now has achieved, and following his Ph.D., Gosling found no opportunity to continue at King's, although he would have liked to do so. Gosling went on to lecture in physics at Queen's College, University of St Andrews in Scotland, and then found a long-term position at the University of the West Indies. For a few years he continued with crystallography research, focusing on analysis of the structure of nucleotides, but then shifted toward research in the field of medical physics, working on designing equipment to study and diagnose atherosclerosis. He returned to the UK in 1967 and became Lecturer and Reader at Guy's Hospital Medical School, and Professor and Emeritus Professor in Physics Applied to Medicine from 1984. Here he helped develop the underlying basic medical science and technology for haemodynamic doppler ultrasound vascular assessment in the Non Invasive Angiology Group, and set up the clinical Ultrasonic Angiology Unit. Gosling served on numerous committees of the University of London, notably relating to radiological science, and retained an active professional involvement in medical physics almost to the end of his life. Gosling was married to his wife Mary; they had four sons, the eldest of whom is the furniture designer Tim Gosling. Raymond Gosling died at the age of 88 on 18 May 2015.
