Here is a summary of my career in academia.

Research Projects involvement :

SIBILA - Towards Smart Interacting Blocks that Improve Learned Advice

The SIBILA project aims at developing a set of tools that will effectively support the decisionmaking process in organizations, and facilitate the process of building data-driven solutions. These tools will be able to process and represent complex sources of data, such as multirelational and/or web data, and to, given a user-defined task, semi-automatically select the best components at hand and compose them together. To do so, SIBILA will require progress at the level of knowledge representation and data mining techniques. Moreover, the complexity of SIBILA will require contributions in software engineering and language development. Next, we discuss in more detail the main challenges facing SIBILA: knowledge representation and inference, web data, learning technology, and system engineering.

DigiScope - Digitally Enhanced Stethoscope for Clinical Usage

The DigiScope project aims at developing a digitally enhanced stethoscope capable of using state of the art technology in order to help physicians in their daily medical routine.The DigiScope project aims at developing a digitally enhanced stethoscope capable of using state of the art technology in order to help physicians in their daily medical routine.

DRIVE-IN - Distributed Routing and Infotainment through Vehicular Inter-Networking

DRIVE-IN addresses both foundations and applications of inter-vehicle communication. Concepts, methodologies and technologies will be developed in the three main research thrusts: Geo-optimized VANET protocols, intelligent and collaborative car routing, and VANET applications and services. These research thrusts shall fertilize horizontal activities covering realistic large-scale simulation and massive real-life experiments in urban environments. Project DRIVE-IN (Distributed Routing and Infotainment through VEhicular Inter-Networking) is a research project approved within the 2008 Call for Proposals for the Information and Communication Technologies Institute (ICTI) and the Carnegie Mellon University - Portugal Program (Carnegie Mellon|PORTUGAL) by the Fundação para a Ciência e a Tecnologia (FCT). DRIVE-IN is included in the research program on New Generation Dependable Trusted Networks and Telecommunications Policy (NGN), addressed by the 2008 Call. The goal of DRIVE-IN project is to investigate how vehicle-to-vehicle communication can improve the user experience and the overall efficiency of vehicle and road utilization.

N-Crave - Network Coding for Robust Architectures in Volatile Environments

The simple, yet disruptive idea of Network Coding (NC) is that nodes will no more only forward but also process and mix the incoming independent information flows. The revolutionary paradigm has the potential of realizing multi-fold performance gains. It is thus expected to change the way we perceive, architect, organize and control networks and foretells deep impact in a wide range of areas such as network topology formation, error resilience, resource sharing, flow control interactions, and tasks such as content delivery, network monitoring and security.
