Wallace Martins

 Bio

I am a Full Professor at ISAE-SUPAERO, Université de Toulouse, France, since September 2023. My research interests encompass digital signal processing and telecommunications, focusing on future wireless and satellite networks.

Prior to joining ISAE-SUPAERO, I worked as a researcher at SnT, University of Luxembourg, from 2019 to 2023. I was also affiliated with the Federal University of Rio de Janeiro (UFRJ), Brazil, as an Associate Professor from 2013 to 2022. At UFRJ, I was responsible for various activities, including serving as the Academic Coordinator for the Electronics and Computer Engineering undergraduate course and the Deputy Department Chairman (DEL/Poli/UFRJ) from 2016 to 2017. Before that, I held the position of Assistant Professor at CEFET/RJ, Brazil, from 2010 to 2013. Additionally, I had the opportunity to work as a Research Visitor at the University of Notre Dame (USA, 2008), Université de Lille (France, 2016), and Universidad de Alcalá (Spain, 2018).

Throughout my professional career, I have collaborated on research projects with various companies such as HP Labs, GE, Siemens, Halliburton, Thales Alenia Space, and SES. I also supervised several undergraduate, master’s, and Ph.D. students in digital signal processing and telecommunications.

I was the recipient of the Best Student Paper Award from EURASIP at EUSIPCO-2009 in Glasgow, Scotland, the 2012 Best Brazilian D.Sc. Dissertation Award from Capes, and the Best Paper Award at SBrT-2020 in Florianópolis, Brazil.

I am an IEEE Senior Member and an ADR holder (Right to Supervise Doctoral Candidates, equivalent to HDR, granted by the University of Luxembourg).

 Research

The main application area of my research efforts is Digital Communications, and I usually approach the related problems through the lens of Signal Processing Theory & Methods (SPTM). More specifically, my ongoing efforts focus on addressing physical-layer problems of satellite communications (SATCOM) within the NewSpace context.

In my research topics, I try to balance some fundamental long-term research with some hot-topic current interests of the research community. The following non-comprehensive list of research topics reflects this fact (for the big picture of my research dissemination, refer to my resumé) :

• Distributed signal processing for satellite communications (e.g., beamforming for satellite swarms)
• Waveform design for future wireless networks (e.g., for enhanced multiple access and resource allocation in IoT networks)
• Set-theoretic online machine learning (e.g., for data-selective reinforcement learning applied to SATCOM resource allocation)

 Service

I currently serve as :

• Senior Area Editor for the IEEE Signal Processing Letters
• Editor for the IEEE Communications Letters
• Associate Editor for the EURASIP Journal on Advances in Signal Processing
• Member of the EURASIP Technical Area Committee (TAC) Theoretical and Methodological Trends in Signal Processing (TMTSP) — Chair of the subcommittee for TMTSP Nominations/Elections
• Guest Editor of the Special Issue on Satellite Communications for 6G for the EURASIP Journal on Wireless Communications and Networking
