A team from the Department of Mathematics will be taking part in two exhibits at the Festival of Wonder at the University of Surrey on Saturday 13 May. They will be exhibiting in the “Wonder” marquee. Ester Bonet Luz, Jane Lyle and Ying Huang will be in the Tech zone discussing their work with Philip Aston on physiological time series and enabling people to make a “selfie” of their heart. Gianne Derks and Anne Skeldon will be in the Health zone, demonstrating how mathematical models of sleep/wake regulation can help us understand how our sleep patterns change with age; see the link about this here. This latter exhibit is based on joint work with Prof Derk-Jan Dijk of the Surrey Sleep Research Centre.
