Mission statement

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

From high energy beams scattering in a disordered medium to Shannon informational capacity of the modern day optical fibre communications scientists and engineers have to look at and describe the systems that are affected both by nonlinearity and noise. While the area of high power and high signal-to-noise ratio is studied by the nonlinear physics (with many achievements to its credit) the opposite limit deals with fully disordered systems and/or incoherent pulses and is the subject of the general theory of disordered systems. The grey area in between, when both signal and noise contribute equally to the dynamics of the system remains one of the main challenges for both physicists and engineers.

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!

A short bio sketch

I received my M. Sc. in theoretical physics (first class honours, summa cum laude) in July, 1999 at Kharkov State University in Ukraine and the Ph.D. in the same area in September, 2001 at the Institute for Radiophysics and Electronics,  Kharkov, Ukraine. From January 2002 to September 2007 I was a research fellow at Photonics Research Group at Aston University, Birmingham, UK. From October 2007 to September 2012 I was an EPSRC Advanced Fellow first at the Photonics Research Group and later at Mathematics Group at Aston University. In 2012 I moved to Israel where I won a Marie Curie Inter-European fellowship at Weizmann Institute of Science from April 2013 to March 2015. In October 2015 I joined School of Electrical and Computer Engineering at Ben Gurion University in the Negev where I am currently holding a rank of an associate professor (now hapily tenured!)
