Short biography
Nikolaos Chrysos received his PhD in
Computer Science from the University of Crete in 2006. In his PhD
thesis, he conducted pioneering work on congestion management that was
supported by an IBM PhD Fellowship, where he proposed architectures
that were adopted by several commercial switches in the following
years. From May 2009 to September 2014, he was with IBM Research in
Zurich, where he worked with IBM Systems & Technology Group (STG) on
the Implementation and Performance Optimization of Next- generation
Networks for PureFlex Systems. Since October 2014, he is with
ICS-FORTH as a Postdoctoral Fellow, and he is also a Visiting
Instructor at the Computer Science Department of University of
Crete. Under the ExaNeSt, EuroEXA (H2020 FET-HPC) projects, he led the
Network Interface Group that designed and built RDMA-capable network
interfaces with congestion management capabilities. He is currently
principal investigator in the RED-SEA EuroHPC project. He has served
in the Technical Program Committee of 15 conferences and workshops. He
is the author or the co-author of 16 patent applications (14
Granted). According to Google Scholar, he has an h-index of 15 and his
publications have received more than 891 citations.
