About
Konstantinos Nakos received his B.Sc. in Physics in 2001 and his M.Sc. in Electronics and Automation in 2003 at the National and Kapodistrian University of Athens. He attained his Ph.D. degree in 2008 with thesis title "Efficient Parallel Architectures for Video Coding in Real-Time" from NKUA. He has been with the DST since 1997 acting as a research associate and has participated in numerous of the team's projects as a designer, a researcher and a research lead.
