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. In 2012 she was awarded by the best final project in Telecommunications Engineering in the area of Information Systems. In 2013 she was awarded by COIT the best national Master Thesis on Analysis and Optimization of Wireless Networks, sponsored by Ingenia TelecomFrom 2010 to 2011, she was with Abertis Telecom, Barcelona, as an internship for projects related to infrastructures for surveillance and smart cities. From 2012 she is a research assistant in the SPCOM research group at UPC, where she has participated in the EC funded projects FREEDOM and TROPIC and in a Huawei-UPC collaborative project on flexible duplexing for 5G systems. In 2013 she was recipient of a Spanish Ministry of Education grant (FPU) to complete the Ph. D. thesis at UPC. The thesis focuses on the development of coordinated and cooperative techniques for distributed interference management in MIMO dense heterogeneous cellular networks. In 2015 she did a research appointment at Nokia Networks and Aalborg University in Aalborg, Denmark, within the framework of the PhD research topic. Her main research interests include optimization theory, interference management, MIMO, and dense networks. She has one patent application filed and has participated in several contributions to the 3GPP-LTE release 11 and 12.
