Associate Professor of Computing Security

Education: 

  • Ph.D. in Computer Science, University of Cambridge, UK, 2000
  • M.S. in Computer Science, Harvard University, USA, 1997
  • B.S. in Computer Science, University of Crete, Greece, 1996

Speciality: Computer Design and Architecture

Dr. Ioannis Papaefstathiou current research interests focus on architectures for network processors and specific purpose networking systems. He has published more than 80 papers in IEEE/ACM sponsored journals and premier international conferences while there are over 650 citation to his research work . He has been a guest editor of a special issue of IEEE Micro. He has also been a member of the Program Committee of several IEEE conferences, a reviewer for a number of international IEEE, ACM and Elsevier journals and for more than 20 IEEE and ACM sponsored conferences. He has been Principal Investigator in 12 competitively funded research projects in Europe (in 7 of them he was the technical manager), in the last 6 years, where his cumulative budget share exceeds 3.2 million €. 

Research Areas: I am interested in the architecture and design of novel computer systems, focusing mostly on media and network processing devices and the interaction between VLSI and computer architecture. Currently I concentrate on the design and implementation of specific purpose microprocessors with tightly coupled design parameters and highly constrained resources such as network processors. Successful designs in this area require optimization in both hardware and software and they integrate ideas from computer networking with ideas from system design and computer architecture. I am also interested in high-speed systems for encryption, compression or any other data manipulation method.
