[3] She studied physics at the University of Sussex in 1969, however she also had a fondness for archaeology, which she credits her mother and Sir Mortimer Wheeler’s TV and radio programmes.
[4] Wintle became an Emeritus Professor at Aberystwyth University in the Department of Geography and Earth Sciences in 2001.
[4][3] Her work focuses on luminescence dating, a field at the intersection of archaeology, geology and physics.
She studies and applies techniques to date samples from sedimentary deposits containing minerals such as quartz or feldspars.
[4] In 2008, she won the Institute of Physics Edward Appleton Medal and Prize for her outstanding contribution in the development and application of luminescence properties of minerals as a geological dating tool applicable to the past one million years.
