Education

• PhD in Engineering, University of Cambridge, UK. (Viva Exam in December 2011; degree conferred in July 2012.)
  
  
• M.Sc. in Electrical and Computer Engineering (2 years degree), Telecomunications profile, Instituto Superior Técnico, University of Lisbon, Portugal, 2003
  
  
• Licenciatura in Electrical and Computer Engineering (5 years degree), Telecomunications profile, Instituto Superior Técnico, University of Lisbon, Portugal, 1998.

• September 2024: Our paper "Efficient entanglement purification based on noise guessing decoding" has been accepted and already published in the prestigious Quantum journal, Sep. 2024. [Quantum] [ArXiv]

• We have submited the paper "Entanglement Routing Based on Fidelity Curves"  to the prestigious IEEE Network magazine, Aug. 2024. [ArXiv]
  

• July 2024: We've submitted the paper "Fault-tolerant noise guessing decoding of quantum random codes" to IEEE Transactions on Information Theory, proposing a quantum-GRAND decoder that is able to cope with preparation errors, measurement errots, and noisy gates, to a leavel that can be made practical [ArXiv].

• January 2024: We've submitted the paper "Simple and Fast Decoding of Short LDPC Codes" to ISIT 2024. We are happy and honoured for the wonderful collaboration with Prof. Carlos Salema. The paper proposes a groundbreaking technique for low-lattency decoding. [Paper].
  

• November 2023: By using a duality between error correction and link purification, we have proposed a much more efficient technique for purification of quantum links: Purification-GRAND (PGRAND). Submitted to the high-impact Quantum journal [ArXiv].

• October 2023: Our Quantum-GRAND (QGRAND) proposal for quantum error correction has just been accepted for publication in IEEE Access [IEEEXplore].
  
  
• July 2023: We have generalised symbol-level GRAND to massive MIMO and proposed using a soft metric to sort the antennas and greatly reduce the decoding time up to 80%. Submitted to IEEE Trans. on Wireless Comms: [ArXiv].
  
  
• April 2023: We have proposed a new metric and a new tool to be used in routing in quantum networks. The proposed metric is based on "fidelity vs entanglement probability" curves. Submitted to Physical Review A: [ArXiv].
  

• February 2023: Three journal papers published in their final version in Jan-Feb 2023:
  i) Symbol-level GRAND in IEEE Communications Letters [IEEEXplore];
  and two papers on routing on quantum networks:
  ii) point-to-point entanglement in IEEE Access [IEEEXplore];
  iii) multipartite entanglement in the Quantum journal [Quantum].

• September 2022: GRAND decoding over massive MIMO presented and published in VTC-Spring 2022, London [IEEEXplore].
  

• August 2022: Decoding any error correction code! A triplet of papers based on noise-centric decoding was just made available:
  i) applying for the first time GRAND in coded massive MIMO and seeing how RLCs outperform 5G's polar codes [ArXiv];
  ii) showing that switching from bit-level GRAND to symbol-level GRAND can reduce computational complexity by half or more [ArXiv];
  iii) extending GRAND to decoding quantum RLCs, with the proposal of Q-GRAND. [ArXiv]
  It was very rewarding to work on these ideas at this stage with co-authors with whom it is a pleasure to work with while exploring ideas in fundamental research.
  
  
• June 2021: Very proud  to seeing our work on MIMO for wireless energy transfer published in the prestigious IEEE Journal of Selected Topics in Signal Processing [IEEEXplore] [ArXiv] [5min video].
  
  
• On sabbatical leave from Feb. 2019 until Feb. 2020, visiting/collaborating with a number of research groups abroad.

• April 2019: Leading IUL's rank of reviewers according to Publons and in the top positions worldwide in the relevant research fields: 4G, 5G, info.theory, dig.comms, MIMO comms, wireless and mob. comms. In the wider areas: EEC (top 2%), ECE , sig.proc. (top 1%). In the top positions within IT (which spans many areas).

• August 2018: We have successefuly organised ISWCS 2018 in Lisbon (205 participants from all over the world, first-class keynote speakers, state-of-the-art tutorials,...)

• May 2017:  Our paper on Fast Matrix inversion for massive MIMO is listed in the "Top Downloads in IEEE Xplore [Reader's Choice]" compiled by the IEEE Signal Processing Magazine in the May 2017 issue, listing the top-10 most downloaded papers during the last 2 two years from the IEEE Sig. Proc. Letters.
