Sandra Lagén received the Telecommunication Engineering degree, the Master’s degree, and the Ph.D. degree from Universitat Politècnica de Catalunya (UPC), Barcelona, Spain, in 2011, 2013, and 2016, respectively.

From 2010 to 2011, she was with Abertis Telecom, Barcelona, as an internship for projects related to infrastructures for surveillance and smart cities. From 2012 to 2017 she was a research assistant in the Signal Processing and Communications group at UPC, where she carried out her Ph.D. thesis “Coordination Strategies for Interference Management in MIMO Dense Cellular Networks” thanks to a Spanish Ministry of Education grant (FPU). At that time, she participated in two FP7-ICT projects funded by the European Commission (FREEDOM and TROPIC)  and a collaborative project with Huawei on flexible duplexing for 5G systems. In 2015, she did a research appointment at Nokia Networks and Aalborg University in Aalborg, Denmark. Since 2017 she is a Researcher in the Mobile Networks Department of the Communication Networks Division at CTTC, where she has participated in a collaborative project with InterDigital on 5G NR and NR-U design for mmWave bands and coexistence studies with other technologies in unlicensed spectrum, and an on-going grant from the NIST (U.S. Commerce Department’s National Institute of Standards and Technology) to enable and accelerate NR Vehicular to Everything (V2X) communications for sub 6 GHz and mmWave bands. The 5G NR, NR-U and NR V2X technologies are modeled and simulated in a network simulator (ns-3) built by CTTC-MONET, whose details can be found here.

In 2017, she was awarded by COIT the best national Ph.D. thesis on high-speed broadband mobile communications, sponsored by Orange. The Ph.D. thesis also received a Special Doctoral Award by UPC in 2019. Also, in 2012 she was awarded by the best final project in Telecommunications Engineering in the area of Information Systems, and in 2013 by COIT the best national Master Thesis on Analysis and Optimization of Wireless Networks, sponsored by Ingenia Telecom. She is the recipient of the IEEE Wireless Communications and Networking Conference 2018 (WCNC18) best paper award. She has two patent applications granted, three provisional applications, and has participated in several contributions to 3GPP-LTE. Her main research interests are in designing and analyzing wireless network protocols with emphasis on cross-layer optimizations, especially with PHY and MAC layers, for multiple bands and shared/licensed/unlicensed paradigms.
