Rui Dinis received the Ph.D. degree from Instituto Superior Técnico (IST), Technical University of Lisbon, Portugal, in 2001 and the Habilitation in Telecommunications from Faculdade de Ciências e Tecnologia (FCT), Universidade Nova de Lisboa (UNL), in 2010. From 2001 to 2008 he was a Professor at IST. Currently he is an associated professor at FCT-UNL and a senior researcher at IT (Instituto de Telecomunicações). During 2003 he was an invited professor at Carleton University, Ottawa, Canada. Rui Dinis is an IEEE Senior Member and is or was editor at IEEE Open Journal on Communications, IEEE Transactions on Wireless Communications, IEEE Transactions on Communications, IEEE Transactions on Vehicular Technology and Elsevier Physical Communication, as well as guest editor for special numbers of several journals. He was part of the Organizing Committee of multiple IEEE conferences (ICT’2014, VTC’2017-Fall, VTC’2018-Spring, ISWCS’2018, VTC’2019-Spring, VTC’2020-Spring, VTC’2020-Fall, GLOBECOM’2020). He is also president of VTS Portugal Chapter since 2016 and a member of several IEEE technical committees (CTTC, SPCC, RCC and WCT). He is a Senior Member of the IEEE, a Member of the IEEE Communications Society, IEEE Vehicular Technology Society and IEEE Information Theory Society. Since 2018, he has been a Distinguished Lecturer of the IEEE Vehicular Technology Society. He was Invited Lecturer, Invited Speaker and Invited Panelist at several international events and PhD. schools. Rui Dinis has been actively involved in several international and national research projects in the broadband wireless communications area. He was involved in pioneer projects on the use of mm-waves for broadband wireless communications and his main research activities are on modulation and transmitter design, nonlinear effects on digital communications and receiver design (detection, equalization, channel estimation and carrier synchronization), with emphasis on frequency-domain implementations, namely for MIMO systems and/or OFDM and SC-FDE modulations. He is also working on cross-layer design and optimization involving PHY, MAC and LLC issues, as well as indoor positioning techniques.
