1 month ago, I defended my #phd entitled "Characterization of multilayer networks: theory and applications to the brain", under the memorable supervision of @F_DeVicoFallani. Thanks to @_AlexArenas @LindaDouw, @alainbarrat, @gin_bianconi for our insightful discussions.

We exploit the complementarity of the two descriptions to provide a local connectivity-based characterization of very diverse multiplex networks. Actually, we need both descriptions to properly classify groups of multiplex networks !

Which description best discriminate MEG activity of Alzheimer's disease patients as compared with the healthy controls one ? šŸ§  The dark side seems promising in this way. How about we explore it further ?šŸ§

One week ago, the in-person @APSMeetings 2023 ended. Warm thx to all of the organizers and volunteers that made it possible. Special thx to @GuidoCaldarelli for chairing the session where I presented. Lots of new ideas to explore, now ! #APSMarch2023 #Physics #Science #Networks

Make sure to be present in Room 125 @APSMeetings for a Focus session on Network Theory and Applications. My talk on node-layer duality in multilayer networks is expected at 9:36 a.m PT. See you there ! #apsmarch #physics #network
