 | | Noisy Lotka-Volterra dynamics of a predator-prey population on a single patch, where the population (xy coordinates) are oscillating and the oscillation amplitude is fluctuating in time. The color represent the rate of population changes, from blue (slow) to red (fast). For popular description of our work on that system see PRL focus

Dynamics of complex systems have recently attracted a lot of interest. Years of study in disciplines such as physics, chemistry, biology and even social sciences and finance show that the emerging features of these interacting, nonlinear systems are not easily related to the elementary laws governing their microscopic, individual constituents. The techniques used in the study of nonlinear, out of equilibrium physical phenomena have proven to be very efficient in the analysis of complex systems.
Our group focuses upon various aspects of complexity science. Our primary interest lies in nonlinear systems, such as those describing reactive processes and population dynamics, under the influence of noisy environments and on heterogeneous substrates. We are involved in a variety of works and projects dealing with applications of complexity science. For example, we examine adaptation of autocatalytic fluctuations to diffusive noise, vegetation and spatio-genetic patterns, analysis of quenched heterogeneity (glasses), etc.
