Nikolaos Chrysos received his PhD in Computer Science from the University of Crete in 2007 on congestion control for multi-stage fabrics, which earned him an IBM Phd Fellowship. Between 2007 and 2008, he was a Visiting Instructor at the Electronics and Computer Engineering Department of the Technical University of Crete, and a Postdoctoral Fellow at ICS-FORTH. From 2009 to 2014, he was a Visiting Scientist at IBM Research--Zurich, where he contributed to the design and the implementation of a high-performance server-rack fabric for 100G Ethernet. While with IBM, N. Chrysos also co-led the design of a switch chip supporting 136 ports at 25 Gb/s, and participated in the HISTORIC EU-funded research project on all-optical networks. Since October 2014, he is with ICS-FORTH, working on high-speed datacenter networks, microservers and low-power systems. Dr. Chrysos has many peer-reviewed publications in top conferences and journals, is the (co-)inventor of seven granted patents, and a recipient of four IBM Patent Plateau Awards. He is a member of HiPEAC and of ACM.
