Seminar Abstract:

 

Biological outbreaks are a widespread phenomena found in both ecological and epidemiological systems.

In this talk I will outline some fascinating mathematical approaches for studying the thresholds controlling these outbreaks, and the factors which trigger them.

Epidemics of infectious diseases such as measles, influenza etc make nice case studies since we can make use of available collections of good quality long-term data. 

In particular, I will show how ideas from nonlinear dynamics can be applied directly in modelling such time-series, and how they help us when attempting to "forecast the future."

In seasonally driven systems, outbreaks can appear annually (eg., because of climate drivers) but they may also trigger erratically in an unpredictable fashion.

The behaviour matches that of a forced oscillator in the chaotic regime and this is where the modelling gets interesting.......

Bio:

Professor Lewi Stone joined the School of Mathematical and Geospatial Sciences, RMIT University in March 2013.

Prof. Stone comes from Tel-Aviv University, Israel, where he worked for over two decades largely in the area of theoretical biology. Originally from Melbourne, Lewi Stone studied at Monash University where he obtained an Honours degree in Mathematics followed by a PhD. At RMIT he will be providing leadership to the Network Modelling Group within the Platform Technologies Research institute.
