Gianne Derks and Anne Skeldon attended and gave talks at the workshop “The Dynamics of Energy, Sleep and Climate” organised by Chris Budd and Lorna Wilson. It was held today (Wednesday 20 February) at the University of Bath and sponsored by the Institute of Mathematical Innovation (IMI). The workshop explored the links between the dynamical systems describing energy harvesters, models of sleep, models of climate and other phenomena. Anne gave a talk on “Mathematical models of sleep/wake regulation” and Gianne talked about “Bifurcations and dynamics of ‘threshold’ systems“.
