My research concentrates on the dynamics of networks, and specifically the role of connection delays. Such delays appear in a variety of fields, as in most networks the interaction between is not instantaneous: it takes time for information to travel from one node to another in communication networks, or between coupled optical elements. In gene regulatory networks the process of assembling mRNA and proteins can be modelled with a delay time, whereas in neural networks the delay accounts for the conduction of an electric signal along the axon. Models incorporating a delay also appear in population dynamics, traffic dynamics, or between coupled electronic gates… Even if this delay is small compared to the internal time scale of individual network nodes, it can result in a huge traveling time across a complex network.
I am mainly interested in fundamental properties of delay systems, as the role of network structure in the dynamics, synchronisation and symmetry-breaking in time-delay networks, the interplay of time-delay and stochastic effects,…
Being the one of the most important and best understood experimental test-beds in non-linear dynamics, I have particular interest in the dynamics and synchronisation of delay-coupled semiconductor lasers.
