Cambridge University is searching for a PhD student to undertake a dream role for the sweet-toothed - studying chocolate.

The fully funded three-and-a-half year research project will examine how chocolate can remain solid when stored and sold in warm climates.

Much of the work, supervised by academics with "extensive experience in studying soft solids", will be experimental.

It will be based in the university's Department of Chemical Engineering & Biotechnology and will start in January 2015.

A job advert posted on the university's website states that the role's theoretical aspects "will require good mathematical skills".

"The project sponsor has existing technology in this field and the project will develop a fundamental understanding of the area which extends beyond the industrial need.

"The project is mainly experimental and will employ theological and analytical methods from a range of engineering and physical science disciplines," the advert said.
