Studies:12/2004 AEROSPACE ENGINEERING MASTER DEGREE at University of Rome “LA

SAPIENZA” (ITALY).End-of-studies project: “Study and structural analysis of a newconfiguration for a micro/nano/picosatellite dispenser for VEGAlauncher”.

SummaryI have a consolidated professional expertise in aerospace systems design, analysis and testing,gained by working on ASI & ESA contracts for almost six years, and by performing research forsurveys studies since my graduation. Moreover my expertise covers system engineering, withgreater emphasis on space mission design, engineering requirements and it’s quicklystrengthening within management domain, focusing on program and proposal management. As main professional experiences within the space domain, I worked after university degree forseveral years with Mr. Giorgio Perrotta (Spacesys founder and former owner,CEO and CTO) asindependent consultant structural engineer / structure designer. Since June 2008 I’ve beenworking in Spacesys within the Thermo-Structural Dpt. holding positions of structural designer &analyst coordinator supporting Rheinmetall Italia SpA in MAGIA lunar mission (ASI sponsored“Piccole Missioni”) growing to be an aerospace system engineer. I was in charge of theactivities related to mission analysis and requirements definition of all the programs of myCompany with a particular regard to AROSAT VHR EO monitoring and surveillance mission ledby Rheinmetall Italia SpA with Spacesys SRL support. During this activity my duty wassupervision and coordination of small Spacesys internal teams, external teams from the primecontractor and subcontractors. A particular effort was performed in payload requirementsdefinition/estimation especially on I/F structural/thermal requirements (launch stressenvironment analyses performed with MSC PATRAN® and NASTRAN®), I/F electronicrequirements (input and output datarate estimation to/from mass memory and downlinksystem), acquired image errors definition and estimations; for a better comprehension of EOimaging system&products I attended a specialized course in EO imaging tools & GIS likeERDAS® and ARCVIEW®. Another important activity in AROSAT mission concerned duties inmission analysis through orbital definition analyses (drag and gravitational perturbationsestimation for orbital correction definition policy) performed with AG STK® and OrbitalWorkbench®.Within the requirements definition area, the key experience was the entire program PhaseA0/A1 System Review, as responsible of preparation for subsequent phases (under thecoordination of Spacesys CEO/CTO). I’m author of different surveys/trade off on EO spacesystems/subsystems and launchers. I’m author of different papers, published as journal articlesand within conference proceedings, on structural analysis and design for a spacecraftdispenser for the VEGA Launcher and MAGIA Lunar Observation Mission and other EO missions.I was co-responsible in the ESA sponsored PETIT project of environmental (structural andthermal) tests for breadboards and qualification models.I was the proposal manager and responsible of redaction for answers to ESA ITTs for my

Company.I worked in the Air Quality Environmental Sector for The Lazio Regional Environmental Agency(ARPALazio) in a wide range activity from data analysis to hardware maintenance &calibration, redaction of documents for hardware procurement; actually I’m working in EMFmonitoring Unit in Rome having in charge activities regarding V&V of RBS environmentalimpact documents by EM simulation and measurement of radiated narrowband an widebandelectromagnetic emissions from BTS, Radio/TV broadcasting systems and power distributionhardware (utility grid/electricity transformers).Recently in the System Engineering Chapter of Rome Engineering Board my activity wasfocused on the fast growing UAV/UAS market, looking for new opportunities to promote thesegame-changing systems within Italian work civilian environment with conference activities andpapers.All the abovementioned experience gave me the chance to improve my professionalexpertise on customer interface and reporting, subcontractor management, oral presentation,team coordination and multi-disciplinary team working within an international environment,business dealings, ability to work under pressure, and my personal qualities as leadership,reliability, interpersonal relationship, creativity and motivation.
