Mission statement |

I am a theoretical physicist by training and I have spent most of my career looking at nonlinear and/or disordered systems.

Most of my current research activities (as listed below) deal with the interplay of nonlinearity and disorder in one way or another. From optical telecommunications to thermalization in coupled waveguides and from information theory to machine learning - they all have one thing in common: they are enormous fun!

Main research interests |

- Fibre optics communications

- The Nonlinear Fourier Transform and eigenvalue communications. Read more.
- The effects of inline noise on pulse propagation in optical fibres.
- Rogue waves and extreme power outages in optical telecom systems.
- Optical solitons.

- Nonlinear beam scattering in random discrete and continuous medium

- Soliton scattering in the nonlinear disordered optical medium.
- Linear and nonlinear speckle optics.
- Imaging through nonlinear disordered medium
- Thermalization in systems of coupled discrete optical waveguides.
- Discrete
breathers in dissipative systems.

- Shannon capacity of the nonlinear communication channels

- The ultimate capacity limits of the nonlinear optical communication links. Read more about it here.
