George Papadimitriou

George Papadimitriou is an Assistant Professor in the Computer Engineering & Informatics Department at the University of Patras, Greece, hosted within the School of Engineering. His primary affiliation lies with the Computer Hardware and Architecture division, where he leads research and teaching activities focused on dependable, energy-efficient computer architectures.

Education:

• PhD in Computer Science, Department of Informatics & Telecommunications, National and Kapodistrian University of Athens (2019)
• Post-doctoral researcher, Computer Architecture Lab, National and Kapodistrian University of Athens

Research Interests:

Dr Papadimitriou’s research lies at the intersection of computer architecture, energy efficiency, and microprocessor reliability. His work specifically targets:

• Robust and energy-efficient CPU/GPU/accelerator architectures
• Post-silicon validation techniques for catching elusive hardware bugs
• Silent data corruption detection and mitigation across the compute stack
• Characterization of voltage margins and power consumption in modern microprocessors
• Modeling and simulation of domain-specific accelerators for low-power, dependable operation

More recently, his team has been extending these methodologies to RISC-V and neuromorphic photonic accelerators within large European consortia.

Scientific Awards & Recognition:

• Eight HiPEAC Paper Awards for top-tier conference publications (MICRO, HPCA, ISCA) between 2017–2024
• IEEE Transactions on Computers 2022 Best Paper Award for the article “Anatomy of On-Chip Memory Hardware Fault Effects Across the Layers”
• TTTC/ITC Gerald W. Gordon Student Award 2023

Research Funding & Projects:

Dr Papadimitriou is principal investigator or key technical contributor in multiple Horizon Europe and industry-backed projects that collectively exceed €50 M in funding. Current leadership roles include:

• DARE (Digital Autonomy for RISC-V in Europe)
• NEUROPULS (Neuromorphic Energy-Efficient Secure Accelerators)
• REBECCA (Reconfigurable Heterogeneous Highly Parallel Processing Platform)
• Vitamin-V (Virtual Environment & Tool-boxing for Trustworthy RISC-V Cloud Services)
• Intel, IBM, and Thales bilateral research contracts on energy-efficient and resilient microarchitectures

Laboratory & Team:

He leads the Energy-Efficient and Dependable Architectures (EEDA) research group at University of Patras, operating laboratory facilities for silicon measurement, FPGA emulation, and full-system simulation (gem5, MARSS, custom tools). The team currently comprises 3 PhD candidates, 2 post-docs, and several MSc thesis students collaborating with European and US partners.
