Welcome to my page!
My name is Panagiotis (Panos) Garefalakis and I am currently part of the engineering team at Cloudera,
working on query runtime optimizations for the Data Warehouse (CDW) cloud-native product.
Big part of my work is available as open-source, contributed as part of Apache Hive, ORC, and Tez projects.
My current interests lie within the broad area of systems including large-scale distributed systems, cluster resource management, and distributed query processing.
I obtained my PhD degree in Computer Science from Imperial College London, in 2020,
under the supervision of Peter Pietzuch.
At Imperial I was affiliated with the Large-Scale Data & Systems (LSDS)
group and my PhD was supported by a CDT HiPEDS scholarship.
Prior to that, I was a graduate research assistant at FORTH-ICS
affiliation in Greece. I received my Master (MSc) and Bachelor (BSc) degrees in Computer Science from University of Crete
under the supervision of Kostas Magoutis.
