Gustavo Marfia | Università di Bologna (original) (raw)
Gustavo Marfia received a Laurea degree in Telecommunications Engineering from the University of Pisa, Italy, in 2003 and a Ph.D. degree in Computer Science from the University of California, Los Angeles, in 2009.
Between 2002 and 2004 he was with Siemens Mobile Communications Research Labs in Milan, working on advanced services for next generation mobile network customers. While working at Siemens he filed one patent. His work has been part of demonstrations held for the Italian Secretaries of Telecommunications and Innovation, among others.
Between 2004 and 2009 he was with the University of California, Los Angeles, working as a Graduate Student Researcher at the Network Research Lab led by Prof. Mario Gerla and as a Teaching Assistant for the CS118 class on Computer Networks. During this same period he collaborated with STMicroelecronics on the SEA European Project, with Microsoft Research Cambridge and the Los Alamos National Labs as a Research Intern and with the Istituto Superiore Mario Boella as a consultant. As a student his research interests included TCP congestion control for fixed networks, the use of peer-to-peer infrastructures for multimedia streaming, biomedical networks and vehicular ad hoc networks (where he was among the first students working on the Campus Vehicular Testbed Project). He graduated with a thesis on "P2P Intelligent Transportation Systems: Mobility, Fairness and Scalability" approved by a committee composed by Prof. Mario Gerla (Computer Science - UCLA), Prof. William Kaiser (Electrical Engineering - UCLA), Prof. Leonard Kleinrock (Computer Science - UCLA), Prof. Richard Muntz (Computer Science - UCLA), and Dr. Antony Rowstron (Microsoft Research - Cambridge).
Since 2012 he is an Assistant Professor with the University of Bologna, Italy and since 2011 he is a Visiting Scholar at the Department of Computer Science, University of California, Los Angeles. His research interests, while in Bologna, have expanded to also include computer gaming and the use of advanced interfaces for human-computer interactions. His work has been object of public demonstrations at the Shanghai World Expo in 2010 (Tortellino X-Perience Project on computer gaming in public spaces) and at the University of California, Los Angeles, in 2011 (Talking Cars Project on the use of vehicular networking for safety). He moreover works, as a Teaching Assistant, for the Internet Architecture and the Applied Multimedia Systems courses taught by Prof. Marco Roccetti. To this date, he has published more than 80 refereed scientific papers and he is author of a paper cited more than 100 times. His H-Index (according to Harzing's Publish or Perish on the 12th of September 2014) is 15.

Computer science, in fact, has evolved from being the discipline concerned with the design and implementation of hardware and software components, exclusively meant for the execution of computing tasks, to a multifaceted area of science which deals with information systems at large, including the study of the interfaces and algorithms capable of extending/interacting with the human senses, perceptions and brain capabilities. Aesthetics, on the other hand, provides a well-established framework which may very well serve the purpose of analysing and discussing the existing and rising relationships among human beings, computer systems and the physical environment.

quality of the environment through the lens of Online Social Networks (OSNs). These contributions fall in the area of human-centric sensing, area specialized in using what people spontaneously say on social media to detect the occurrence of given events. Research in this area has exhibited interesting results, regardless of the accuracy of sensing operations. In fact, in some cases it is possible to corroborate the information extracted from OSN posts with the ground truth obtained from specialized hardware sensors. In others, the information extracted from OSNs does not reveal true environmental conditions. Nevertheless, OSNs may help shed light on the sensitivity of human beings to a wide variety of environmental phenomena. We here review the work that has been published to this date. In particular, we provide a survey that may benefit both environmental and computer scientists, as this work aims to show where we stand in the understanding of the complex relationship between human beings and the natural environment, when this is mediated by OSNs.

The nonconformity of released data for digital processing also requires vast and costly data input and adaptation. Archaeology should face the cognitive challenges posed by digital environments, changing in scope and rhythm. We advocate the adoption of a synergy between recording techniques, field ana-lytics, and a collaborative approach to create a new epistemological perspective, one in which research questions are constantly redefined through real-time, collaborative analysis of data as they are collected and/or searched for in an excavation. Since new questions are defined in science discourse after previous results have been disseminated and discussed within the scientific community, sharing evidence in remote with colleagues, both in the process of field collection and subsequent study, will be a key innovative feature, allowing a complex and real-time distant interaction with the scholarly community and leading to more rapid improvements in research agendas and queries.

Fostering reliable medical ecosystems requires an exploitation of such data, controlling quality and delineating user behaviors. This strongly emerges with chronic patients: they are expected to devote a long use of the Internet on the same health topics; nonetheless a limited amount of research has investigated their online resources and behavior. We uncover the role of online social networks for a growing community of chronic patients: Crohn's disease patients. Our contribution is twofold: (a) we characterize the data exchanged by Crohn's patients, (b) while analyzing how they deal with given topics of medical interest. In particular, of great medical relevance is the result that Infliximab is the treatment that mostly influences the Crohn's patient community sentiments. We are confident our analysis of the health heritage exchanged online can help improve Crohn's patients' experience, exceeding the traditional practices that typically concentrate on individuals rather than on communities.

TCP has been advertised as a fair-share protocol. However, when session round-trip-times (RTTs) radically differ from each other, the share (of the bottleneck link) may be anything but fair. This motivates us to explore a new TCP, TCP Libra, that guarantees fair sharing regardless of RTT. The key element of TCP Libra is the unique window adjustment algorithm that provably leads to ...

Their popularity in the contemporary world society has led many researchers to think how they could be put to good use to improve the education of players engaged in a game. In this work we present a game that goes beyond this paradigm, which is centered on single persons and pervasively relies on players to pursue a service that may be useful to a community as a whole. The game we here propose collects and processes information about the accessibility of city roads to build paths that may be approached by people with impairments. Players that join the game are rewarded gaining points and positions in the game ranking for each reliable piece of information they provide. Accessible paths, built taking into account such information, can be accessed through a Google Maps-like service which computes the shortest and...

The ability to collect, share and access community health related data are key factors that have made mobile health an appealing addon to medicine practitioners and researchers. Mobile sensing and wireless communications can be exploited to create new information and services that could help prevent health risks, benefiting the community as a whole. As a proof of concept, we have developed an augmented reality application offering an enhanced pedestrian route navigation system, while at the same time gathering quality data through the devices. Thanks to this application we are able to enrich geographical maps on the web with historical data about brightness and noise levels, and to provide pedestrians with an improved navigation.
