Personal profile

Research Statement

My main research activities lie within the wide area of statistical signal processing, with diverse multi-disciplinary applications to wireless communications and array processing, computational biology, and financial engineering, among others. With a focus on inference and estimation theory under high-dimensional settings (big data), my research is aimed at providing contemporary signal processing solutions and machine learning methods, and at enhancing our current understanding of complex biological systems.

At the core of my research, a common factor is the use of advanced concepts from high-dimensional statistics and random matrix theory to develop estimation and inference methods suited to the large-dimensional nature of contemporary data.

A substantial part of my past (and current) research has been focused on the design and analysis of wireless communication systems. With a special dedication to multi-antenna-based technologies, I have conducted research on channel models (fading and interference modelling), and on different topics including: massive MIMO, coordinated transmission (e.g., interference alignment, coordinated beamforming), spectrum sharing, and channel-aware scheduling. I am generally interested in research challenges posed by the ever-growing dimensionality (e.g., users, antennas) of forthcoming wireless networks, and particularly in the development of robust signal processing solutions.

I received the M.Sc. and Ph.D. degrees in Telecommunication Technologies from University of Málaga (Spain) in 2008 and 2011, respectively. Between 2011 and 2013 I was with the Wireless Communications Group (WiCom), headed by Prof. Angel Lozano at the Department of Information and Communication Technologies, Universitat Pompeu Fabra (Barcelona, Spain), where I was a Postdoctoral Fellow and part-time Lecturer. Between 2014 and 2018, I was with the Department of Electronic and Computer Engineering at The Hong Kong University of Science and Technology (HKUST), first as a Visiting Scholar (2014-2016), and then as a Research Assistant Professor (2016-2018). In March 2018 I joined the Faculty of Engineering and Physical Sciences at Queen's University Belfast (QUB), where I am currently a Lecturer (Assistant Professor).

During the summers of 2010 and 2015, I held respective visiting appointments at University College London (UCL), Department of Electronic and Electrical Engineering, hosted by Prof. Kai-Kit Wong, and at Stanford University, Department of Statistics, hosted by Prof. Iain M. Johnstone.
