Ana Moragrega Estrany received the M.Sc. degree in Electronic Engineering from the Universitat de Barcelona (UB) in 2004 and the Ph.D. at the Department of Signal Theory and Communications (TSC) of the Universitat Politècnica de Catalunya (UPC) in 2016. She also received a post-graduate Master in Electronic Engineering (research in Instrumentation and Communications Systems) from the UB in 2006 and previously, 2 courses of the bachelor degree in Physics from UB in 2000.

From September 2004 to October 2006 she joined SIC (Instrumentation and Communications Systems) group of Electronic Engineering Department (faculty of Physics of UB) as research assistant. She participated in an industrial project (TRANSAMI) and in a project funded by the Spanish Government related to wireless sensor networks. Moreover, between September 2005 and September 2006 she was teaching assistant.

She joined CTTC in November 2006. From 2016 she is Researcher. From 2006 to 2016 she worked as Research Engineer (digital signal processing) and received the Ph.D in 2016: “Optimization of positioning capabilities in wireless sensor networks: from power efficiency to medium access”.  At CTTC, she has participated in projects funded by the European Commission (FEMIoT, TIMON, NEWCOM#, SWAP), Spanish Government (ARISTIDES, ADVENTURE) and Catalan Government (2009 SGR 940, FEMIoT) and industrial projects (5GB-CAR, ULTRAMUMO, AT4Wireless, Quetzal). Moreover, she has participated in proposals and reports of projects. She has published and has been reviewer of international conferences and journals. She was awarded a Torres Quevedo Research Grant from the Spanish Ministry of Science and Innovation (2007-2009).

Her current research interests include signal processing and digital signal processing for positioning, communication systems, wireless sensor networks, UWB and GNSS. Moreover, other interests are machine and deep learning and energy saving strategies.
