    Marital Status            Married with two children

    Scholarship

    2002-2005           Ph.D. Telecommunication Engineering and Microelectronics  at the University of Rome `Tor Vergata'. Thesis title: `Optical Communication Systems in Networks and Satellite Links'.

    2001 – 2002         M.S. (`Laurea Specialistica') degree cum Laude in Telecommunication Engineering at the University of Rome `Tor Vergata'.

    1996 -2001          Bachelor `Laurea' degree cum Laude in  Telecommunication Engineering at the University of Rome `Tor Vergata'.

    1991-1996          High School :Liceo Ginnasio `Augusto' in Rome. Final mark 57/60.

    Professional Experience

    2010-present      Fixed-term contract with Ace s.r.l. to develop an optical sensing system based on Fiber Bragg Grating filters. The system aims at monitoring the health of the railway by evaluating the stress and temperature variation during the daytime, considering a train transit as a probe input. The system can measure the speed of trains as well as their weight. These data are used to extract information about traffic and to support train scheduling. Main duties in the project currently concern the installation of sensors on Milan underground, as well as the procurement of hardware and support to software development.

    2008-present      Post-doc at ASI (Italian Space Agency). Research topic: Broadband communication systems based on satellites, stratospheric platforms, and terrestrial networks, telecommunication networks with optical and microwave links. Cost analysis and simulation of architectures and operating scenarios.

    2010                    Consulting contract with `Radiolabs' consortium to carry out a study focused on turbulence and pointing errors in optical links between flying aircrafts.

    2006-2007           Fixed-term research contract with Filas (Lazio regional agency for research and innovation) to develope and install  a fiber-optics-based system for monitoring railway tracks.

    2005-2008           Fixed-term research contract with the Electronic Engineering Department  of the University of Rome `Tor Vergata' to study optical links for space applications (LEO-GEO, LEO-HAP), the use of EDFA in optical intersatellite links, as well as the impact of turbulence in the payload design.

    2004-2005           Fixed-term contract with Telecom Italia Learning Services, for tutoring and supporting internal training courses.

    2003-2004           Fixed-term research contract with CNIT (National Interuniversity Consortium for Telecommunication)  to study MANET networks and Ambient Intelligence.

    Working Skills

    During my experience at University, I had the opportunity to work in international teams. In the same period I developed my natural attitude to creative thinking.

    At the Italian Space Agency I joined the Concurrent Engineering Facility. This let me work in a team of people with diverse expertise, and I learnt how a subsystem must be designed to accomplish also other subsystem issues.

    During the  consulting experiences I developed skills in problem solving.

    Finally, working in a small company developing hardware allowed me to face management and technical issues to reach the goal we aimed at. Often, fast and easy thinking  allowed me to propose some key solutions to reach the target and solve problems.

    Hobbies and Interests

    I love travelling, in particular by trains ( took the Transiberian train); I like music and cinema; I love knitting and cooking.

    Main Research Interests and Publications

    ·        SOA Modeling and simulation of Semiconductor Optical Amplifiers, with experimental trials. I developed an accurate analythical model of field and medium interaction within the active medium of a SOA. By means of that, phase impairments and cross talk due to phase non linearities coming from multiwavelength propagation are measurable [J3, C11, C15, O1]. This is not always possible by using the more common Rate-Equatioin based models [J1, J2, O1]. Prelimiary experimental results, on phase modulation induced by multisignal propagation along SOAs were reported in [C11] and [C15]. I was personally involved in the laboratory experiments.

    ·        Modulation Instability is a nonlinear phenomenon arising under proper propagation condition in dispersive media, like fiber optics. It is possible to exploit this phenomenon to develope a distributed technique to perform signal processing [C4, C18]. Published results come from an analithical approach compared to several laboratory measurements [J4]. I am personally following both the aspects of the work.

    ·        Free Space Optics is an actractive subject to be developed, usefull to solve the last mile problem as well as to carry out efficient intersatellite links or interplanetary communication [C1, C2, C3, C4, C5, C6, C7, C8, C9, C12, C13, C14, C16, C17, O1, O2]. Several architectures are still to be studied.

    ·        Fiber Bragg Grating filters offer the possibility to develope passive and non intrusive sensing system, suitable for extended structures. When the number of sensors increases for a proper communication architecture enhances the capability of the sensing system. I am involved in a project with the task of installing sensors along a railway track and developing the processing software.
