Nikolaos Bartzoudis (Alexandroupoli, Greece 1976) is a Senior Researcher and head of the PHYCOM department at CTTC. Nikolaos obtained his B.Sc. in Electronic Engineering at the Technical Educational Institute of Thessaloniki (Greece, 2000). He then pursued postgraduate studies and received his M.Sc. degree (in Digital Communication Systems) and Ph.D. degree (in dependable embedded systems) from Loughborough University (UK, 2001 and 2006 respectively). Before joining CTTC (January 2008), Nikolaos has worked 2 years as Research Assistant (Loughborough University , UK, 2001-2003) implementing reconfigurable hardware solutions for Active Networks and as a Senior Research Officer (University of Essex , UK, 2005-2008) implementing a flexible low-cost sensor-processing node with built-in self-testing utilities. At CTTC Nikolaos was promoted twice, from Senior Research Engineer to Research Associate (10/2008) and then to Senior Researcher (04/2013). Nikolaos has been/is principal investigator and project manager in 5 funded R&D projects (ReproRun, ITERATE, AEThER, BeMImoMAX, GEDOMIS-ADCOMM). He has also participated in more than 10 other R&D projects funded by public authorities (EC, Spanish government and EPSRC) or the industry. Nikolaos has supervised M.Sc. and Ph.D. students, served as mentor in the Google Summer of Code 2015, gave invited lectures, participated in industrial panels, acted as proposal evaluator and coordinated live demonstrations of prototypes in various events. Nikolaos also possesses hands-on knowledge of the entire technology transfer cycle.

Nikolaos has long experience in real-time baseband prototyping for spectral and energy efficient 4G/5G systems, which encompasses:

- Advanced RTL design techniques using hardware description languages (e.g., VHDL) & schematic-entry SW tools
- HW-SW co-design for FPGA-based SoC devices
- Working with high sample rates and/or under dense FPGA design constraints
- Board-level code integration (firmware), laboratory testing and debugging
- KPI-driven experimental validation
- Examples: multi-carrier (e.g., OFDM, FBMC) and multi-antenna systems, waveform cohabitation, cognitive/reconfigurable radio, hardware-assisted Software Defined Radio

1. Duties as Head of Department

- Define together with the Division Head the scientific and technical objectives of the Department.
- Take all necessary actions to guarantee the Department’s financial sustainability (through competitive funding proposals, industrial offers etc.).
- Manage the effort devoted to R&D projects for Department members.
- Recruit personnel when funds are made available.

2. Duties as technical team leader

- Supervise and coordinate the development and experimental testing of computational intensive DSP algorithms/systems applying high speed digital designs techniques and hardware-software co-design practices.
- Motivate or lead the dissemination of results produced in projects.
- Networking activities leading to national and international collaborations, materialized as publications or demonstrations (e.g., with Intel (Munich), CEA-Leti, Airbus DS (Paris), SMEs and other academic institutions).
- Principal Investigator & project manager in proposals and projects respectively.

3. Other assignments at CTTC
