This workshop brings together a multidisciplinary team of researchers (including mathematicians, modelers, ecologists, epidemiologists, and immunologists) to discuss the current challenges and state-of-the-art advances in the application of bifurcation theory and chaos to analyze the long-term behavior of autonomous and non-autonomous (climate-driven) dynamical systems arising in population biology. Phenomena in ecology, oncology, immunology, epidemiology, social science (human behavior), conservation and sustainability of species and ecosystems, etc., will be targeted. The main themes of the proposed workshop are: bifurcations and chaos in multi-strain disease dynamics, bifurcations in immunology (e.g., between acute and chronic infections), bifurcations in models of tumor growth and treatment, and the onset of and recovery from chaotic behavior in ecological models.
