January-2012: The content of website is scheduled for a major update.
2007: Ph.D. candidate, Univ. Aveiro, Portugal supervised by Prof. Dr. Rui L. Aguiar;
thesis title: "Service Building in Dense Service Provision Environments"
The most important part of my PhD studies is being also supervised by Prof. Peter Steenkiste from Carnegie Mellon University.
2006: M.Sc. in Telecommunications and Electronics Engineering from Univ. Aveiro, Portugal;
thesis: "Contributions to Quality-of-Service in Mobile Ad Hoc Networks" (abstract)
2001: Licenciatura (roughly B.Sc.+Master, 5 years) in Applied Physics from Univ. Coimbra, Portugal;
thesis: "Design, implementation and test of a CCD controller based on microcontroller with applications to clinical ocular fluorometry: the PAF fluorometer".
currently associated to Institute of Telecommunications, University of Aveiro, working in research projects such as Daidalos Consortium (QoS, mobility and multicast with a focus on inter-operator topics)
I work in this research group at University of Aveiro: Advanced Telecommunications and Networks Group (ATNoG)
I maintain a short CV on 
. For details and a full CV please contact me.
i have been involved with many political parties. I am generally on a kind of leftish (the -ish is very important)liberal side (some call it social-liberalism). I've been with Humanist Movement, Movimento Liberal Social, Movimento Mérito e Sociedade, amongst others. Right now I am with PDPD (People-Discussing-Politics-over-Dinner).
LED, Liberdade na Era Digital (loosely, Liberty in the Digital Era), is an association the reflects and acts on the impact of technologies in our everyday life as citizens such as DRM, net neutrality, privacy, etc. Unformally born in 2006, formally born in April 2007. Update: formally killed in July 2011. Now it is an informal Movement.
my personal www: writing, watching, wining (as in "act of having wine"): the geodesical centre of a squase whose sides are James Joyce, José Saramago, Beckett and António Lobo Antunes.
the other side: alternative world-views (in portuguese: mundividencias); history of religion and sacredness; meditation and contemplation
(written in 5 minutes -- and in 2007!)
I am particularly interested in understanding the interactions between domains
(e.g. operators or service providers)
that arise from forced cooperation in order to provide a end-to-end service deifned
in terms of the technology-agnostic end-user. This is the interdomain problem
and whenever two domains engage in cooperation we say an act of federation has occurred.
These acts of federation, in its multiple perspectives (statement, implementation, enforcement,
verifiability, etc.) must be understood.
For example, imagine that a user connects to the internet using a hotspot and tries to
make a VoIP call to a friend in a distant country. On one hand, the data packets may
cross many networks that may belong to different owners (that may even don't know each other
as it happens today); on the other hand, the signalling to setup the call may need
to involve many domains for a number of functions (e.g., billing, call-termination and peer discovery,
QoS request, etc.).
Specifically, my work will deal with three general problems:
· How to enhance the network in order to extend intradomain features (QoS, mobility,
group communications, security, privacy, etc.) to interdomain scenarios?
· from the perspective of a service provider, how does business impact technology? Specifically,
how does competition and cooperation ("coopetition"?) impact end-to-end service building? Network
operators sharing resources (e.g., antennas and backbones) is an illustrative scenario that can take two
shapes: users hop around the filed without any knowledge that they're using
different providers and users choosing a provider. GSM roaming provides a hint
to how things will look like in the future.
· Considering that we face progressive specialization (small providers and/or break-down of
vertical and big providers, e.g., access, transport, service, management, ...), how to
build a service if we have to involve many domains with complex federation acts?
Overall, my research interests are the following:
· Quality-of-Service: assurances in packet switched networks, mapping access services in core services,
QoS models for ad hoc networks
· Mobility: Mobility architectures, global/local problem splitting, mobility impact on network planning
· Interdomain: Impact of interdomain on intra-domain technologies, service building using many providers
