She has been researching the structure and properties of quantum dots, tiny man-made clusters of semiconductor particles with optical and electronic properties that are already used in biomedical imaging, solar cells, and light-emitting diodes.

Using quantum dots will extend far wider once they are better understood and may even be used to cure disease.

The 28-year-old post graduate PhD student from China has developed complete profiles and understanding if these clusters, having carried out investigations at the synchrotron science facility. Her work at Queen Mary's was being judged against 180 science research projects.

Stephen Metcalfe, the parliamentary scientific committee's chairman, said: 'This competition gives MPs a chance to meet the country's best young researchers, early career engineers, mathematicians and scientists who are the architects of our future. It's our best chance to understand their work.'

Lei is competing with 180 'early career' researchers being judged by experts in engineering, sciences, physics or mathematics.
