The master (http://bigdata.uniroma2.it/) is jointly organized by Telecom Italia and Ericsson and is designed to prepare Data Scientists to manage Big Data. I have acquired new knowledge on business and management, as fundamental concepts of decision making process & models, strategic management of big data results, and communication design of results. Moreover, I have enforced my technical skills in language processing (R, Python, Hadoop), database management (MySQL, MongoDB), advanced statistics and machine learning tools.Lessons and exams currently finished, and graduation will be in January 2017.

My research activity mainly focuses on cognitive networks, where I am considering an innovativeapproach that merges the traditional analysis of a communication system with the tools providedby neural networks and machine learning from psychology. I have recently worked on a particularapplication based on a context aware optimization in the framework of handover techniques. Furthermore, I was involved in a work dealing with content based optimization for video resource allocation using Bayesian Networks. Finally, I have investigated optimal caching strategies for mobile users and base stations in heterogeneous networks.

I spent 7 months at UCSD as a visiting student under the supervision of professor Bhaskar D. Rao. We investigated caching strategies in heterogeneous wireless networks that allow file storage bothat the base stations of the small cells deployed within the macro cell, and at the terminal mobile users. In addition, user mobility and class of interest will be also taken into account for cache decisions. The essential rationale motivating our work is the paradigm of proactive caching. Since user behavior is proven to be somehow predictable, pre-fetching crucial contents in advance from the time they are effectively requested is a promising approach to overcome the limits imposed by the caching strategy used so far, namely reactive caching, where the action of storing content is taken to satisfy each user request after it is initiated.

I worked within the framework of the EU funded SAPHYRE project whose main research field was resource sharing among operators. My activity included tasks coordination among partners, finalized at writing the final white paper and deliverable.
