I am interested in the theoretical analysis and performance evaluation of networks, which can be found in almost all forms of biological and engineered systems. Especially, the human brain with its huge number of connected neurons shows great computational abilities and high complexity, which make it a remarkable study object in the field of networks.

My research focuses on the analysis of brain functional networks obtained from fMRI or MEG experimental data by using methods from graph theory and network science. I am particularly interested in studying how the network is decomposed in modules (communities) and how the network adapts itself to different situations under the presence of fluctuations.

Inspired by the mechanisms observed in the brain, I aim to design distributed and noise-assisted strategies that can be implemented in future information networks in order to improve their adaptability and robustness.
