Roy Sambles

Sir John Roy Sambles (born 1945) is an English experimental physicist and a former President of the Institute of Physics.

Sambles, originally from Callington in Cornwall, studied physics at Imperial College, London, gaining his BSc and PhD degrees there, and has since published over 550 papers in international journals. He was elected a Fellow of the Royal Society in May 2002.

Sambles is currently Professor of Experimental Physics at the University of Exeter, he has a long and distinguished career researching the interaction of light with matter. His group at Exeter have studied a wide range of systems including: liquid crystal devices; iridescent butterfly wings; surface plasmons and microwave photonics. These studies have applications in liquid crystal displays for televisions and computer displays, highly sensitive detection of materials (e.g. for medical diagnosis), and optical and microwave communication.

In 2008, he was appointed to the Engineering and Physical Sciences Research Council.

Sambles was knighted in the 2020 Birthday Honours for services to scientific research and outreach.

Personal life
Roy Sambles and his wife, Sandra ( Sloman), had three children.

Sambles is a Methodist local preacher and has served in that capacity for over 30 years, preaching in the Ringsash Methodist Circuit in Mid Devon.
