In field of renewable energy, I worked towards the optimal control of wind turbine against resonance. At the University of Surrey, I was in the group awarded with the PATENT:


Szyniszewski, S., Bhattacharya, S., Cavarretta, I. (2017). Apparatus and method for controlling a resonant frequency of a wind turbine generator.



I have been a reviewer for several international journals, including:



Soils and Foundations,

Particuology Journal,
