    Personal profile

    General

    I am Lecturer in Mathematics at Aston University since September 2016, since November 2017 I combine this appointment with an MSCA Fellowship at the Aston Institute for Photonic Technologies (AIPT). My research is in the field of nonlinear dynamics and photonics, I am specifically interested in coupled semiconductor lasers and in general, coupled oscillators, network dynamics and time-delay systems.

     

    Research Interests

    Delayed Complex Systems

    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 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, the effect of a distributed delay... as well as in specific problems relevant to neuroscience or engineering.

     

    Laser dynamics

    Semiconductor lasers provide one of the best controlled and best understood experimental systems that show nonlinear effects; these nonlinear effects give rise to numerous applications. I collaborate with experimental groups, to study dynamics of coupled semiconductor laser systems.

    My interests include delayed feedback lasers, synchronisation and mean field effects in opto-electronically coupled lasers, mode locking effects in fiber lasers and the application of complex photonic dynamics for novel computational methods.
