About Me
Maria Tsampazi holds a MEng (’21) in ECE from National Technical University of Athens, Greece. She is a Ph.D. Candidate in Electrical Engineering at the Institute for the Wireless Internet of Things. Her research lies on NextG networks and intelligent resource allocation in Open RAN. She has received academic awards sponsored by the U.S. National Science Foundation, the IEEE Communications Society, and Northeastern University, and is a 2024 recipient of the National Spectrum Consortium Women in Spectrum Scholarship. She has previously collaborated with both government and industry, including organizations such as the U.S. Department of Transportation and Dell Technologies.
Expertise
I am a fourth-year PhD candidate and Research Assistant at the Institute for the Wireless Internet of Things at Northeastern University, under the supervision of Prof. Tommaso Melodia. My research focuses on Open RAN systems and the experimental evaluation of NextG RANs in O-RAN. I specialize in AI for and on the RAN, as well as network management and optimization. My expertise includes AI/ML for RAN optimization, beamforming with Reconfigurable Intelligent Surfaces, and energy efficiency in 5G systems. I have extensive experience with experimental testbeds, system-level simulations, and software-defined radio techniques. Additionally, I possess strong technical skills in Python, MATLAB, TensorFlow, and more.
