George Siachamis

I am a PhD Candidate at the Web Information Systems group of the Faculty of Engineering, Mathematics and Computer Science at Delft University of Technology. I am also part of AI for Fintech Research, a collaboration between TU Delft and ING. I am supervised by Asterios Katsifodimos. My research is focused on adaptive stream processing, and specifically adaptive similarity joins over data streams, autoscaling and live state migration, while I have also worked on data discovery.

Before pursuing a PhD, I did my research internship at CY Cergy Paris University under the supervision of Katerina Tzompanaki. Prior to that, I obtained my 5-year Diploma in Electrical and Computer Engineering from National Technical University of Athens.
