Tiago Varum (S’13 – M’17) was born in Estarreja, Portugal, in 1987. He got his M.Sc. degree in electronic and telecommunications engineering and Ph.D. degree in electrical engineering from the Universidade de Aveiro, Aveiro, Portugal in 2010, and 2016, respectively. Since 2017 he is Research Assistant at the Instituto de Telecomunicações, in Aveiro. His main research interests include antenna design, Reconfigurable antennas, 3D-Printed antennas, non-uniform antenna arrays, beamforming and smart/adaptive antennas, for mmWave applications (Radar, 5G or SATCOM). During this time, he has participated in some projects and published several papers in this field, in conference proceedings and journals. He has also supported teaching activities in the department of electronics, telecommunications and informatics (DETI) of Universidade de Aveiro. Dr. Tiago is member of IEEE Antennas and Propagation Society.
