Ms Qing Wang is from China and now a researcher for MEFISTA at Aston University in the UK. She is looking at the uses of dual frequency combs and how they can be used in every day life. It's a long, detailed process, involving many experiments. But the results, improving and changing people's lives in the areas of science and technology, are worth it. Qing is interviewed by Karola Woods, also at Aston.
