My research  focuses on dynamics of networks, specifically on the role of a time-delay. Such a time delay appears for example when coupling optical units; I started my career studying the dynamics of delay- coupled semiconductor lasers, and I have a specific interest for the dynamics optical delay systems. 

Coupling delays can be found in a variety of fields, such as electronic, communication, biologic, neural... networks. I study generic dynamic effects of a delay, such as interplay of delays and noise, the interaction of delay and network symmetry, delay-induced synchronisation patterns,...

Research Background  

I completed my whole education that the Vrije Universiteit Brussel (Belgium). In 2007 I graduated as licentiate in physics; in the framework of my master thesis I studied the dynamics of delay-coupled lasers, under guidance of Jan Danckaert and Ingo Fischer at the Applied Physics Research Group.  I conducted my PhD in the same group, as a fellow of the Research Foundation Flanders (FWO-Vlaanderen). My PhD research concentrated on synchronisation in small networks of delay-coupled generic oscillators and their relation to semiconductor lasers.

After receiving my PhD in 2011, I joined the computational physics group of Wolfgang Kinzel at the University of Würzburg (Germany) as a postdoc. There I investigated fundamental properties of delayed chaotic systems, and the interplay of noise and delay. I moved to the United States for a second postdoc in October 2014. In the group of Daniel Gauthier at Duke University (Durham, North Carolina) I worked on dynamics and information processing in experimental time-delay electronic networks.

Since September 2016 I am a lecturer at Aston University.

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.
