Research topics	Networked Music Performance: Networked Music Performance promises to revolutionize music rehearsal and teaching by allowing multiple remote players to simultaneously perform together from different physical locations by means of an Internet connection over a telecommunication network. However, in order to reproduce realistic rehearsing conditions, multiple technical, psycho-cognitive and purely musical issues must be addressed. In particular, at network level, very strict requirements in terms of latency and jitter must be satisfied to keep the one-way end-to-end transmission delay below a few tens of milliseconds. This research aims at investigating how the timbral characteristics of the instruments and the rhythmic complexity of the performed piece influence the musicians' performance. To this aim, psycho-acoustics have been performed by modeling the end-to-end (local microphone to remote speaker) channel, considering signal analog/digital conversion, signal codec, signal packetization, signal transmission and the computer real-time-processing limitation. A hardware solution based on an embedded processor and an FPGA is currently under study to minimize such latency contributions. Energy Management in Smart Buildings: The incorporation of Smart technologies in buildings is considered as the key factor for the achievement of the objectives of energy efficiency, integration of Renewable Energy Sources, and reduction in the emissions of pollutants. The research activity is aimed at the design of energy management frameworks for residential and campus buildings. The designed infrastructures provide effective management tools for the local schedule of the energy usage at the users' side, supporting the integration of distributed energy sources (e.g. photovoltaic and wind power plants), energy storage banks, and various categories of controllable loads (including water/heat pumps, Heating, Ventilating and Air Conditioning (HVAC) plants, and electric vehicles). Such local Energy Management Systems must ensure to the users quality of service guarantees while enabling Automatic Demand Response with variable energy tariffs and interactions between users and utilities/ grid operators in case of emergencies. To these aims, the frameworks must also include prediction models for energy production/consumption patterns and building thermal inertia based on weather forecasts and expectations about building occupation, and a system to collect human feedbacks about the perceived thermal comfort. Internet traffic analysis and classification: Internet traffic classification techniques aim at associating to a packet sequence between two hosts and two corresponding transport ports (flow) the generating application. The research activity is focused on the design of statistical classifiers aimed at discriminating different categories of Internet traffic, relying only on statistical attributes of the traffic flows/sources, thus complementing the more intrusive Deep Packet Inspection techniques. Moreover, analyses on network neutrality preservation in the collection of crowdsourced traffic measurements and in the management of content caches have been conducted. Communication privacy and security in Smart Grids: Privacy of user-related data is of paramount importance in Smart Grid scenarios: the increasing diffusion of Automatic Meter Reading (AMR) and the possibility to open the system to third party services has raised many concerns about the protection of personal data related to energy consumption. On one side, information regarding customers' personal habits can be inferred by analyzing metering data; on the other side, detailed knowledge of consumption measurements is crucial for the timely management of energy distribution, provisioning, and forecasting. Research topics: - Privacy-friendly data aggregation and anonymization in the automatic metering infrastructure of Smart Grids: Design of privacy-preserving infrastructures and communication protocols for the secure collection of metering data, which allow utilities and third parties to obtain time and/or space aggregated energy consumption measurements or disaggregated but pseudonymized meter readings, thus making them unable to associate the individual measurements with the identity of the customer (i.e., the meter) that generated the data. - Privacy-friendly distributed optimization of energy consumption in Smart Grids: Design of secure mechanisms and protocols enabling the distributed optimization of energy consumption without compromising the privacy of the users, with the aim of shaping the load profile of a neighborhood according to the local energy production by renewable sources. - Privacy-friendly vehicle-to-grid interactions: Development of mathematical models and heuristics to optimize the power exchange among the batteries of electric vehicles and the smart grid, taking into account the constraints introduced by the power grid infrastructure and the dynamic and partially unpredictable trend of energy production and demand, as well as possible security and privacy implications. Optical network design: The research activity investigates the benefits brought by the introduction of distance adaptive transceivers supporting multiple modulation formats and baud rates in flexible grid networks in terms of spectrum occupation and transceiver utilization. I have proposed methodological approaches for the design of architectures for optical ring metro networks and mesh backbone networks relying on Integer Linear Programming formulations for optimal network deployments, as well as heuristics and analytical bounds for near-to-the-optimum solutions. Complexity analyses of the proposed formulations have also been performed. The impact of usage of spatial division multiplexing by exploiting multimode/multicore optical fibers is currently under investigation, as well as Machine Learning approaches for quality of transmission evaluation and imprecise Markov chain models for performance evaluation of resource allocation policies.
