CURRENT RESEARCHES:

• COMMUNICATIONS VIA METAMATERIALS: Reconfigurable and programmable metasurfaces can be implemented to obtain dynamically switching electromagnetic (EM) functions, thus yielding more freedom and flexibility with respect to conventional phased antenna arrays. Our study shows that joint exploitation of space and time dimensions of EM metamaterials offers additional degrees of freedom that can be exploited for different purposes: (i) improved information rates; (ii) channel estimation; (iii) physical-layer security; (iv) sensing and data fusion; (v) wireless E-health.
• PHYSICAL-LAYER SECURITY: While the enabling technologies for wireless communications gradually mature, all kinds of potential threats or attacks will also rise and endanger wireless systems. These adversarial behaviors are due to malicious users, such as criminals, terrorists, and business spies, and are driven by various motivations, such as committing crimes, jeopardizing public safety, invading secret databases, and so on. We study algorithms working at the physical layer of the OSI model to counteract various wireless attacks, such as jamming and spoofing.
• MATHEMATICAL AND LEARNING TOOLS FOR IMMUNOLOGY: The advances in genetics, biochemistry, and bioinformatics have led to significant advances in experimental and clinical immunology, by revealing complex interactions between the innate and adaptive immune systems, as well as the pathogens that trigger the immune responses. The research activity will rely on a fruitful exchange of theory and tools between cutting-edge branches of immunology and information/communication engineering with the aim of developing mathematical and learning tools designed to address some of the open questions unravelled by the aforementioned advances.
• AMBIENT BACKSCATTERING COMMUNICATIONS: Ambient backscatter is an intriguing wireless communication paradigm that allows small devices to compute and communicate by using only the power they harvest from far-field radio-frequency (RF) signals in the air. Ambient backscattering devices reflect RF signals emitted by existing or legacy communications systems, such as digital TV broadcasting, cellular, or Wi-Fi ones, which are designed for transporting information and are not intended for RF energy transfer. We deal with mathematical modeling, practical design, and performance analysis of wireless broadband networks operating over fading channels with ambient backscatter devices.
