About

I am a postdoctoral researcher in the Wireless@HKU research group at The University of Hong Kong, supported by an individual International Postdoc grant from the Independent Research Fund Denmark. Concurrently, I am affiliated with the Connectivity section at Aalborg University. I received the M.Sc. and the Ph.D. degrees from Aalborg University in 2017 and 2022, respectively. In 2017 I visited Robert Bosch GmbH in Stuttgart, Germany, and in 2020 King’s College London, United Kingdom. I have a amateur radio license (OZ0AEK) and, when time permits, I enjoy being practical with software-defined radio, antennas, channel/source coding, etc.

Research

My research interests are centered around communication theory and wireless communications for 6G and beyond. Recently, I have been focusing on timely communication, designing protocols for massive IoT, and providing ultra-reliable connectivity. My current activities lie in the intersection between wireless communications, machine learning and data mining for IoT.
