About Me

I am a PhD student at Universitat Rovira i Virgili in the Department of Computer Engineering and Mathematics under the supervision of Dr. Pedro García and Dr. Antonio F. Gómez Skarmeta. My PhD thesis will be about middleware services built on top of structured peer-to-peer overlay networks by means of Dermi and p2pCM.

On November 2004 I passed my Diploma of Advanced Studies at Universidad de Murcia. On 2003 I passed my doctorate courses with an average of Excellent. Previously, I obtained my BSc in Computer Engineering (Hardware speciality) in 2000, and my MSc in Computer Engineering in 2002. Both degrees were attained at Universitat Rovira i Virgili.

Affiliations

I am a member of the Architecture and Telematic Services Research Group at Universitat Rovira i Virgili. Our research group merges a multidisciplinar team which tackles key investigation lines of telematic services. We focus on investigating and developing new distributed services and middleware to support collaborative work and telematic services applied to remote teaching. This line is completed with the works in modelling and data visualization in multimodal environments applied to educative medical environments. Moreover, we have researchers working on intelligent systems and the development of analysis and data processing algorithms. Finally, our group is also active in the micro-architecture field and more specifically, in the design and optimization of high performance architectures.

I was member of the ECOO team (Environnements pour la Coopération) at LORIA (Laboratoire Lorrain de Recerche en Informatique et ses Applications), currently affiliated to INRIA (Institut National de Recherche en Informatique et en Automatique) during 4 months in Nancy (France), from August to November 2002. Under the supervision of Dr. François Charoy and Dr. Pascal Molli, I helped on the design and implementation of the Bonita and the Coopéra projects.

I am currently member of the PLANET project, which is a research project from the Spanish Ministry of Science and Technology. (Ref. TIC2003-09288-C02-00). The main goal of this project is to develop a low-cost multiuser collaborative platform for advanced training in settings like Architecture, Medicine or scientific simulation.

Research Interests

Middleware for Wide-Area Distributed SystemsMy main research focus lies in the area of wide-area distributed object technology. I am interested in how to develop a wide-area middleware platform so as an easy transition from local or middle-sized distributed applications to wide-area ones can be achieved. In such line, I have designed and implemented Dermi, a decentralized peer-to-peer distributed object middleware. By using Dermi's underlying services, a new component model for structured peer-to-peer overlay networks called P2PCM has been sketched.
Peer-to-Peer Networks and Applications Application-level multicast for group management in P2P networks is a valid alternative to IP Multicasting when talking about wide-area applications, which provides better group management, reliability and scalability. Recently, a new class of P2P systems is emerging: Distributed Hash Tables (DHTs). They provide insertion and lookup mechanisms to store/retrieve key-value pairs efficiently, thus making at most O(log N) hops between nodes.
Collaborative Virtual Environments My previous research interests included Collaborative Virtual Environments where I was one of the main developers of MOVE, a 3D Educational Collaborative Virtual Environment whose main aim is to simulate a virtual classroom, providing a set of shared objects which allow collaboration between users within the same place.
Other interestsMy other research interests include e-Learning, Computer Supported Cooperative Work (CSCW), grid computing, peer-to-peer grid services, etc.
