Research I'm interested in large-scale distributed systems -- particularly in peer-to-peer and grid computing systems -- and in peer production systems (as defined by Benkler). I work with Profs. Francisco Brasileiro and Walfredo Cirne (currently at Google) at the LSD lab. During the spring and summer of 2008, I am enjoying the Vancouverite weather and visiting the NetSysLab lab at UBC, working with Prof. Matei Ripeanu. Current projects Long term reputation in BitTorrent communities: designing a robust mechanism for encouraging seeding based on the usage patterns seen in the trace of a large community. BitTorrent as a peer production system: understanding user behavior and the quality of service which is provided through the commons approach. Collaborative behavior in tagging communities: investigating the structure of interest sharing in tagging communities. With Elizeu, Matei and Adriana. Custom metadata and collaborative annotation to optimize distributed systems: early-stage work on using user-generated annotations to better allocate resources on grids and application and infrastructure-generated annotations to better manage data in storage systems. Past projects The Network of Favors is an incentive mechanism for p2p systems sharing multiple resources (such as CPU, data transfers and storage) which is currently deployed in OurGrid, a free-to-join, peer-to-peer grid in production since 2004. OurGrid and the Network of Favors have received some press attention, for example on the HP Lab's website and on GridToday. The SE3D project was a rendering service for 3D animation companies running on on a 100-node datacenter (probably rendering on the cloud, these days). The project was slashdotted when the service was used by 10 british animation companies to create a showcase in 2004. I participated in the implementation of the system and of its market-based resource allocation mechanisms during a 9-month stay at HP Labs Bristol. MyLib was a prototype of a p2p PDF-sharing community based on semantic queries. The user specifies a tree of inter-relationed terms with weights and the system uses branches of this tree to calculate how accurate are the results. Developed using JXTA, in collaboration with Hyggo Oliveira. The Sonic Object Analysis Library (SOAL) is a library in CommonList / CLOS for the musical composition and analysis software OpenMusic, from IRCAM. This library aids non-tonal musical analysis based on an objected-oriented musical analysis. Participated when working at the Grupo de Pesquisa em Música, Musicologia e Tecnologia Aplicada (GMT) at UFPB |

Et cetera I'm into photography and I maintain a Flickr for that, with all pictures licensed under the Creative Commons license. I'm also very much into music. In the past I've played the bass in a few bands, studied some classical doublebass and currently I maintain a project for DJing brazilian music called Volante Filipéia. |
