Rate My Professor Haridimos Vergos

Haridimos Vergos is a Professor of Hardware and Computer Architecture in the Department of Computer Engineering and Informatics at the University of Patras, contributing to computer science through his extensive research, teaching, and leadership since joining the faculty in 1998. He earned his Diploma in Computer Engineering and Informatics, an integrated Master's degree, in 1991 and his Ph.D. in 1996 from the same department, with his doctoral research on the design of a fault-tolerant cache memory system that introduced methods for fault tolerance in caches and a statistical performance model. After completing his Ph.D., he worked as an ASIC designer at Atmel Hellas from January to September 1998, developing a VirtualNet 802.11b SoC and a multiplexer for networks. His academic career progressed from Lecturer (1998-2003), Assistant Professor (2003-2009), Associate Professor (2009-2014), to full Professor since February 2014. He has served as Head of the Division of Hardware and Computer Architecture three times (2008-2009, 2014-2015, 2023-2024), Director of the Laboratory for Computing (Computer Center) in 2011-2012 and 2013-2014, and currently as Director of the Microelectronics Laboratory (2022-2025) and the Hardware Technology and Computer Architecture Laboratory.

Vergos' research specializations include arithmetic circuit architectures with emphasis on modulo 2ⁿ ±1 arithmetic, VLSI design and testing, low-power built-in self-test (BIST), rapid prototyping of computer systems using programmable logic, IP watermarking, quantum-dot cellular automata (QCA) nanotechnology, neural networks, and path delay fault testing in integrated circuits. A Senior Member of the IEEE, he has authored over 100 publications garnering more than 1,700 citations on Google Scholar. Key publications include "Efficient modulo 2ⁿ -4 arithmetic units" (2025, ISVLSI), "On Modulo 2ⁿ+1 Adder Design" (2012, IEEE Transactions on Computers), and "Area-time efficient multi-modulus adders and their applications" (2012, Microprocessors and Microsystems). In education, he teaches undergraduate courses Introduction to Computer Systems and E-CAD for Digital Hardware, and the graduate course Fault Tolerant Computer Systems; he has authored textbooks, lab manuals, developed the AT91 platform for labs, supervised 56 theses and co-supervised two Ph.D. dissertations, and shares extensive video lectures on YouTube with over 1,600 followers. He also reviews for leading conferences and journals.
