I am an Associate Professor in the Department of Electrical and Computer Engineering and a member of the Institute for the Wireless Internet of Things at Northeastern University. Between January 2011 and Decemebr 2020, I was in the Computer Science and Engineering Department at the University at Buffalo, first as an Assistant Professor (2011-2016) and then as an Associate Professor (2016-2020) and Director of Graduate Studies (2018-2020). I received my PhD in Electrical and Computer Engineering at Purdue University in 2010. Previously, I received my Bachelor's degree from the School of Electrical and Computer Engineering at the National Technical University of Athens (NTUA).

My research interests are broadly in experimental wireless networking and mobile computing, with a current focus on 5G networks and latency-critical applications (AR, VR, CAVs) over 5G, millimeter-wave networking, and energy-aware protocol design for smartphones. I lead the NU Wireless Networking and Systems Lab (NU WiNS Lab). I have served as the General Co-Chair for IEEE WoWMoM 2023 and ACM EWSN 2018 and TPC Co-Chair for IEEE LANMAN 2023, IEEE HPSR 2023, IEEE DCOSS 2022, IEEE WoWMoM 2021, and IFIP Networking 2021. I received the IEEE Region 1 Technological Innovation (Academic) Award in 2019, the UB Teaching Innovation Award in 2018, the NSF CAREER Award in 2016, the UB School of Engineering and Applied Sciences Senior Teacher of the Year Award in 2017 and the Early Career Researcher of the Year Award in 2015, and the UB CSE Senior Researcher of the Year Award in 2019 and Early Career Faculty Teaching Award in 2015.

News

• 04/01/2023: Postdoc opening on next-generation cellular networks, including O-RAN and 5G/6G wireless systems. The candidate will work with a team of students and PIs of the NSF-funded X-Mili project to develop an open and programmable 5G testbed, based on standard-compliant components and radios operating in the sub-6 GHz and mmWave frequencies. The candidate will also contribute to research use cases on the testbed, to develop and test data-driven algorithms for the optimization and control of the base station protocol stack and configuration. We are looking for candidates with a strong understanding of systems and networks, in particular of 3GPP radio access network architectures and protocols, and with solid programming skills in C/C++/Python and familiarity with Linux systems and software-defined radios. Knowledge of FPGA (Xilinx RFSoC architectures) and/or CUDA programming and/or antennas and RF design are appreciated but not required. Interested candidates should email me CV and research statement.
