Portrait of Konstantinos Karanasos

Konstantinos Karanasos

Senior Scientist


I joined the Cloud and Information Services Lab (CISL) at Microsoft in March 2014. After spending a year in Cambridge, UK, where I was hosted by the Systems & Networking group of Microsoft Research, I moved back to California in 2015. My current research interests lie in the areas of large-scale distributed systems, cluster scheduling and resource management, distributed query processing and query optimization.

Prior to joining Microsoft, I was a postdoctoral researcher at IBM Almaden Research Center, where I was member of the Big Data analytics group. At Almaden, I was working on Jaql, a platform for analyzing large datasets in parallel using Hadoop’s MapReduce framework, that is part of IBM BigInsights product.

I obtained my PhD in Computer Science from Inria and the University Paris-Sud, France, in 2012, under the supervision of Ioana Manolescu and Francois Goasdoue. In the context of my PhD thesis, I worked on the areas of view-based query processing, semi-structured data management and data management techniques for the Semantic Web. In Spring 2011, I was visiting the University of California at San Diego, working with Yannis Papakonstantinou on a framework for the efficient data dissemination in Web platforms. Prior to that, I received my Diploma in Electrical and Computer Engineering from the National Technical University of Athens, Greece, where I completed my Diploma thesis under the supervision of Timos Sellis.
