Welcome to my Homepage

I was born in Ierapetra, Greece, in 1977. I received the diploma and the PhD degree in Electrical & Computer Engineering both from the Aristotle University of Thessaloniki (AUTh), Department of Electrical & Computer Engineering in 2001 and 2006 respectively. I am now with the School of Electrical and Computer Engineering of AUTh.

In 2001 I was awarded the "Ericsson Award of Excellence in Telecommunications" (1st prize) for the best diploma-thesis of the year in the field of "Communications". In 2011, we received the 2nd best student paper award in the 2011 RFID-TA Conference that was held in Sitges, Spain for the paper "Inventory Time Reduction in Gen2 with Single-Antenna Separation of FM0 RFID Signals", co authored with J. Kimionis, A. Bletsas and G. Karystinos. I have received twice the "IEEE Wireless Communications Letters Exemplary Reviewer" award for 2012 and 2014 from the IEEE Communications Society, entering top 3% of reviewers for 2012 and 2014 respectively. On February, 2014, I was elevated to the grade of IEEE Senior Member. In 2022, our paper "Device-free Human Tracking Exploiting Phase Disturbances and Particle Filters", was a top-two finalist for the IEEE RFID 2022 Best Paper Award. In 2023, our paper "A Real-Time Multi-Antenna SAR-Based Method for 3D Localization of RFID Tags by a Moving Robot" was awarded with the "2023 James Clerk Maxwell Award" for seminal contributions to the IEEE CRFID community, including the development of accurate and effective techniques for the 3D localization of items tagged with UHF-RFID tags (best paper award in IEEE JRFID 2021-2022).

I 've been a member of the IEEE and the Technical Chamber of Greece since 2001. I serve as a reviewer for several journals and conferences like the "IEEE Journal of RAdio Frequency Identification" , the "IEEE Transactions on Antennas and Propagation", the "IEEE Transactions on Wireless Communications", the "IEEE Transactions on Vehicular Technology", the "IEEE Communications Letters", the "IEEE Wireless Communications Letters", the "IEEE Antennas and Wireless Propagation Letters", the "IEEE Transactions on Industrial Informatics", the "IEEE Transactions on Biomedical Circuits and Systems" and more. I am a Technical Program Committee Member in several major conferences. On September 2015, I was the organizer of the 5th Management Committee / Working Group Meeting and Workshop on "Wireless Power Transmission for Sustainable Electronics" that was held in Thessaloniki, Greece. The workshop took place within the COST IC1301 programme.

Since January 2021, I serve as Associate Editor in the IEEE Journal of Radio Frequency Identification. Since 2021, I also serve as a vice-chair in the IEEE Technical Committee on Motion Capture & Localization, where we aim to promote and facilitate research and publication related to motion capture, localization and related fields.

Demos

Some demos of my work can be found in the Software and Hardware Pages.

Teaching

Since 2014, I participate (either alone or with colleagues) in several courses in the School of Electrical & Computer Engineering of AUTH. This year, my assignment include:

    Winter
  • Analysis and Synthesis of Telecommunications' Devices (9th Semester) - mainly includes front-end high-frequency electronics and related analysis.
  • Calculus I (1st Semester)
  • Electrical Circuits II (3rd Semester)
    Spring
  • Applications of Telecommunications' Systems (8th Semester) - (mainly includes wireless sensor networks)
  • Electrical Circuits I (2nd Semester)

Since 2014, I have also participated in the following courses:

  • Control Systems(5th Semester)
  • Electrical Circuits III (4th Semester)
  • Telecommunication - Networks (8th Semester)

In the context of the course "Applications of Telecommunications' Devices", the students are guided to design and realize a Wireless Sensor Network. Each node consists of a micro-controller, sensors and a programmable RF22 wireless card. By the end of the semester, each group of 2 students realizes a prototype WSN application (hardware and software), deploying all sensing and communication aspects of the system (MAC layer, routing, etc.). Furthermore, all teams are requested to produce a demo-video of their work. Such videos can be found in the following links: Coach Assistant - Athlete Monitoring, Road- Rut Mapping, Find the Sheep, Patient Monitoring, etc. In the context of other courses in the past, interested students participate in the design and construction of prototype devices. On January 2012, students designed and constructed prototype UHF RFID tags. Read details on the Hardware section of the site. Watch the uploaded demo-video in youtube or watch some representative photos from the course. On January 2014, students programmed radio transceiver over an Arduino Uno board to create sensor networks. Again, videos can be found in the following two links: Video1, Video2
