Transients, or non-asymptotic dynamics, cover a wide range of possibilities, from biology to ecology and beyond. A full understanding of transients and their implications for biology requires mathematical and statistical developments as well as attention to biological detail. Transient dynamics have also played a central role in both empirical observations and in models in neuroscience. Yet interaction between ecologists and neuroscientists on this topic has been limited. Although epidemiology could be considered part of population biology, there is also less cross-talk between epidemiology and other areas of population biology than desirable. Transients clearly play a role in disease dynamics. Areas such as immune response require attention to transients as well. Goals for the workshop: To spur further research into transients, both from a mathematical standpoint and as a way to understand and analyze biological systems To develop appropriate statistical questions related to the analysis of biological systems using ideas from transient dynamics To prepare one or more synthetic documents on the role of transients across biological systems Participation in the workshop is by application only. Individuals with a strong interest in the topic are encouraged to apply, and successful applicants will be notified within two weeks of the application deadline. If needed, financial support for travel, meals, and lodging is available for workshop attendees.
