Currently, I’m working at CONNECT – the Science Foundation Ireland Research Centre for Future Networks and Communications as Marie Skłodowska-Curie EDGE Postdoctoral Fellow. The project is named COCODIMM: Complexity and Control of (Distributed) Massive MIMO. In brief, we are observing Massive MIMO from the perspective of complex systems science and looking for the ways to exploit complex behaviours accordingly. The project supervisor is Assist. Prof. Nicola Marchetti, PhD and the co-supervisor is Research Fellow Irene Macaluso, PhD. A lot of work in this project is in the field of reversible computation, and the study is not restricted to radio communication: acoustic underwater communication and molecular communications are of interest as well.
In the past, I was doing research in rather diverse fields, including dynamical systems and chaos (my bachelor and master theses), vibration signal processing (my PhD thesis), modelling and control, (applied) functional analysis, mobile robotics, embedded systems. Some of the results can be found in the publication list below.
I was an active member of the IC1405 COST Action on Reversible Computing, and I have recently joined the CA15220 COST Action on Quantum Technologies in Space.
