reza.jpgThe main current work of mine is concerned with applying the theoretical methods that has been

Developed for the analysis of stochastic fluctuations and complex networks. Developing new algorithms

and quantifying the characteristics of stochastic processes, complex networks and random matrix theory

are some of the main challenges in my current research on such complex systems. I am interested in

gaining deeper insights into stochastic processes, especially those that are non-stationary, coupled series

and identify applications in other fields to which I can apply the methods and expertise. In order to

improve my abilities in understanding the nature of the processes, I intend to investigate whether the

methods that I have developed can be applied to such important problems as rough surfaces and finance

& social problems.



Research Abstract: My research work is in the field of complex systems. More in detail, I currently focus on the following topics:

- Community structure of complex networks

- Statistical physics approach to social & Econo physics

- Stochastic processes, especially those that are non-stationary & coupled series

- The effect of rough surfaces in wave scattering and transport... which is considered in as a stochastic process or in fractional space.
