Here you will have a glimpse into my research and educational activities.
My team designs and optimizes antenna arrays for next-generation wireless systems!
Our applications are cellular & satellite communications, radioastronomy, civilian radars and healthcare.
Since April 2021, I work as an Assistant Professor at the Delft University of Technology (TU Delft), The Netherlands, in the Microwave Sensing, Signals and Systems (MS3) Section. I received my B.Sc. degree with double specialization in Communications and Microwaves/Antennas from the Department of Electrical and Electronic Engineering, Middle East Technical University, Ankara, Turkey, in 2014, and the M.Sc. (Cum Laude, with the Justus & Louise van Effen Scholarship) and Ph.D. degrees (Cum Laude) in Electrical Engineering from Delft University of Technology, Delft, The Netherlands, in 2016 and 2020, respectively. My Ph.D. thesis was titled "Antenna Array Synthesis and Beamforming for 5G Applications: An Interdisciplinary Approach". Following my Postdoctoral Research at TU Delft, I started working in my current role.
My research interests include phased arrays for next-generation communication and sensing systems, array optimization, cooling, multibeam antennas, front-end architectures, and beamforming algorithms.
We submitted two papers to the IEEE AWPL Special Cluster on "Recent Advances in Applications Involving Mutual Coupling".
I gave an invited talk at IEEE/AP/MTT/EMC/ED Turkey Seminars about "Multibeam Antennas for XG".
My course EE4016: Antenna Systems successfully ended.

We, the Microwave Sensing, Signals and Systems (MS3) Section at TU Delft, are an inter-disciplinary and multi-national team of researchers from academia and industry, in which antenna, signal processing, and circuit design experts collaborate to create novel wireless system solutions for the emerging communication and sensing applications.
We have built our expertise on years of research and development in the area of active phased arrays, in strong collaboration with the external partners (e.g. NXP, TNO, Thales, ESA). We are one of the leading research teams in Europe in the development of the next-generation integrated antenna array technology. We aim for the design of highly integrated arrays for efficient and cost-effective antenna and front-end solutions.
We are actively looking for self-motivated researchers to join our team who will be involved in the ongoing antenna design-oriented research projects in collaboration with our industrial partners.
