About
I am a project assistant professor in the Ohtsuki Lab at Keio University, Japan. Concurrently, I hold a part-time position at Aalborg University, Denmark. I received the M.Sc. and the Ph.D. degrees from Aalborg University, Denmark, in 2017 and 2022, respectively. Supported by an International Postdoc grant from the Independent Research Fund Denmark (IRFD), I was a postdoctoral researcher at The University of Hong Kong from 2022-2023, and at Aalborg University from 2023-2024. I was awarded the Spar Nord Foundation Research Award for my Ph.D. project (2023). In 2017 I visited Robert Bosch GmbH in Stuttgart, Germany, and in 2020 King’s College London, United Kingdom. I have an 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 semantic communication, timely communication, designing protocols for massive IoT. My current activities lie in the intersection between wireless communications, machine learning and information theory for IoT.
