Anne Skeldon was in Australia the past two weeks. First, she was a plenary speaker at the workshop on “Dynamical Systems in Physiology” held 6-7 September at Deakin University (shown left) in Melbourne.  Her talk was on “Mathematical modelling of human sleep/wake patterns: the interaction of light, sleep, circadian and social rhythms”. Then from 9-13 September, she participated in a mathematical retreat at MATRIX in Creswick, which is just north west of Melbourne (link here). At the retreat she attended a workshop on “Mathematics of Physiological Rhythms” and gave a talk on “Light and its role in human sleep and circadian rhythms: mathematical modelling and open questions”.
