He is currently an Associate Professor with the Department of Teleinformatics Engineering of the Federal University of Ceará. He received a double Ph.D. degree in Sciences and Teleinformatics Engineering from the University of Nice, Sophia Antipolis, France, and the Federal University of Ceará, Fortaleza, Brazil, in 2007. From 2007 to 2008, he held a one-year teaching position at University of Nice Sophia Antipolis, France. He was awarded multiple times visiting professor positions at the University of Nice Sophia-Antipolis, France (2012, 2013, 2015, 2018, 2019). He served as an Associate Editor for several journals, such as the IEEE Transactions on Signal Processing (2012-2014 and 2014-2016), the IEEE Signal Processing Letters (2016-2018 and 2018-2020). He currently serves as a Senior Area Editor for the IEEE Signal Processing Letters and as an Associate Editor for the IEEE Transactions on Vehicular Technology. He has served as Guest Editor for the EURASIP Journal on Advances in Signal Processing (2014), and the Wireless Communications and Mobile Computing (2018). He is an elected member of the Sensor Array and Multichannel (SAM) Technical Committee of the IEEE Signal Processing Society (SPS) (2015-2018 and 2018-2021), finishing his second term in December 2021. He is an elected member of the EURASIP Signal Processing for Multi-Sensor Systems Technical Area Committee (SPMuS TAC) (2016-2018 and 2019-2022). Dr. Almeida has been involved in several IEEE SPS activities during the past years. He served as associate member of the Big Data Special Interest Group (SIG) of the SPS (2015-2018). He was involved in the organization and chairing of several SPS conferences. In particular, he was a General Co-Chair of the 2017 IEEE International Workshop on Computational Advances in Multi-Sensor Adaptive Processing (CAMSAP’2017), Technical Co-Chair of the IEEE GlobalSIP’2018 and IEEE GlobalSIP’2019 Symposia on Tensor Methods for Signal Processing and Machine Learning, Technical Co-Chair of the 11th IEEE Sensor Array and Multichannel Signal Processing Workshop (SAM’2020), and currently serves as the General Co-Chair of the IEEE CAMSAP’2023. In addition, he has regularly reviewed papers for SPS conferences, such as ICASSP, CAMSAP, and SAM. In 2018, he was elected an Affiliate Member of the Brazilian Academy of Sciences. He is co-recipient of the 2018 IET Communications Premium Award (2018), Best Paper Award at the 19th IEEE International Conference on OFDM and Frequency Domain Techniques (2016), and Best Paper Award at the XXXVIII Brazilian Symposium of Telecommunications and Signal Processing (2020). He has published over 200 papers in journals and conferences, 6 book chapters, and is co-inventor of 3 international patents. He is a Senior Member of the IEEE. research interests include topics such as channel estimation and equalization, multi-antenna systems, blind and semi-blind signal processing. An important part of his research has been dedicated to multilinear algebra and tensor decompositions with applications to communications and signal processing.
