I am a Senior Research Scientist and a Distinguished Member of Technical Staff (DMTS) at Nokia Bell Labs,
working in
the Future Indoor Network (FIN) Team - previous Small Cell Team - of the Access Laboratory.

I earned my
PhD degree in Wireless Communications at the University of Bedfordshire (UoB), Luton, UK in 2011, and received my Bachelor and Master degrees in Telecommunications from the Miguel Hernandez University (UMH), Elche, Spain in 2003 and 2006, respectively.

  As a post-doc,
I was a Research Associate at the Centre for Telecommunications Research (CTR) at King's College London (KCL), London, UK from Aug. 2011 until Jan. 2012.

As an invited researcher, I was visiting the DOCOMO Innovation Labs in Palo Alto, California in 2011, and the Institut National des Sciences Appliquees in Lyon, France in 2009.

I am author of the book, "Small Cell Networks: Deployment, Management, and Optimisation", IEEE Press/Wiley, 2017, where my colleagues and I cover the small cell topic and our pioneering work at Bell Labs.

I am also editor of the book, "Heterogeneous Cellular Networks: Theory, Simulation and Deployment", Cambridge University Press, 2013. 

I have published over 120 book chapters, journal and conference papers, all in recognized venues and have filed more than 45 patents.

I am an editor of IEEE Transactions on Wireless Communications (2016).

I am or have also been guest editor of a number of journals, e.g., IEEE Journal on Selected Areas in Communications,  IEEE Communications Magazine, IEEE Wireless Communications Magazine, IEEE Access, ACM Springer Mobile Networks and Applications (MONET) and EURASIP Journal of Computer Networks and Communications (JCNC).

I am or have also  been chair of a number of workshops, e.g. the 9th, 8th, 7th, 6th, 5th and 4th International Workshop on Heterogeneous and Small Cell Networks (HetSNet), in conjunction with IEEE Globecom, among others.

Moreover, I have also been presenting tutorials and participating in panels at both IEEE Globecom and IEEE ICC since 2011.

Since 2012, I am founding member of IEEE Technical subcommittee on Green Communications and Computing (TSCGCC) Special Interest Group on Green Cellular Networks (SIGGCN).

I received the  Bell Labs Distinguished Member of Technical Staff Award for "sustained outstanding technical contributions to Nokia" in 2019. 

I have received a number of awards for patent filing, granted patents, and standard essential patents at Nokia Bell Labs in 2018 and 2019.

I received the IEEE WCNC'18 Best Student Paper Award of the track "Wireless Networks" in 2018.

I was selected as Nokia Talent in 2017.

I received the IEEE Com Soc Best Young Professional Industry Award in recognition of "my outstanding contributions to the industry in terms of innovative Communications Research and Development, specially in the area of networking techniques for cellular networks" in 2016.

I was among the 6 finalist for the Scientist of the Year prize in The Irish Lab Awards in 2013 and 2015.

I have been honored as invited lecturer in the Bell Labs Presidential Lecture Series - "an invitation that a Bell Labs researcher can expect to receive once every 100 years" - in 2015.

I have received the ALU Bell Labs, Dublin Certificate of Outstanding Achievement in 2013, 2014 and 2015.

I have received the ALU Bell Labs Award of Excellence in 2013.

I was nominated Exemplary Reviewer for IEEE Comm. Lett. in 2011.

I was awarded as PhD Marie Currie Fellow (2007).

In 2007, I received Marie-Curie Fellowship for PhD studies at CWiND at UoB, Luton, UK, where I participated in both the FP6 Marie Curie research project "RANPLAN-HEC ” (MESTCT-2005-020958), and the first EPSRC-funded research project on femtocells “The feasibility study of WiMAX based femtocells for indoor coverage” (EP/F067364/1).

In 2006, I took up a research scholarship at the
Centre for Adaptive Wireless Systems (AWS) at Cork Institute of Technology (CIT), Cork, Ireland, where I worked for a year on a project called “UbiOne – The Multi-Modal WiFi Positioning System”. The main goal of the project was to prove that the major disadvantages of the poor accuracy of existing indoor location systems can be overcome by fusing two complementary location techniques, radio signal strength indication (RSSI) and radio signal time of flight (TOF) with a unique self-calibrating approach.

In 2005, I was with
VODAFONE SPAIN, working at the Radio Frequency Department in the area of network planning and optimization, where I participated in the development of the VODAFONE Automatic Frequency Planning tool for GSM and DCS networks.
