He holds a B.Sc. in Electronics and Telecommunications Engineering (University of Aveiro), an M.Sc. in Biomedical Engineering (University of Aveiro), a Ph.D. in Electrical Engineering (University of Aveiro), and a Postgraduate Diploma in Project Management (Porto Business School/University of Porto). In 2015, he was awarded the First Prize of the Fraunhofer Portugal Challenge (Ph.D. category), a distinction that rewards research of practical utility and in 2007 he received the Texas Instruments ESPA - Excellence in Signal Processing Award. He is the co-inventor of two patents, and authored more than 100 scientific publications in international peer-reviewed journals and international conference proceedings. He has been a researcher in several national and international R&D Projects, five of which in coordination activities. Since 2016, he is European Commission Expert (expert in the ICT-01-2016: Smart Cyber-Physical Systems). He has been the General-Chair at the Edge-IoT - International Conference on Intelligent Edge Processing in the IoT Era since 2020, Co-Chair of the WDTE - Workshop on Digital Transformation in The Enterprise since 2019, and Co-Chair of the Vertical Track: Energy and Power at the IEEE World Forum on Internet of Things 2022. He is the Professional Activities Coordinator at the IEEE Portuguese Section and Counselor in the Executive Committee of the IEEE IPVC Student Branch. He actively collaborates with the IEEE Communications Society and the IEEE Internet of Things (IoT) Initiative, and has been a keynote speaker at international events such as the IEEE IoT Vertical and Topical Summit at the IEEE Radio Wireless Week 2022. His research interests include cyber-physical systems, IIoT/IoT, embedded systems, edge computing/intelligence, digital signal processing, and indoor positioning. When not working, he enjoys traveling, digging records, and playing with analog synths.
