I am a 2nd-year PhD student in the Computer Science Department at the University of Crete, working with Prof. Angelos Bilas. I am also a graduate research assistant in the Institute of Computer Science (ICS) at the Foundation of Research and Technology - Hellas (FORTH). I received my Bachelor’s and Master’s degrees in Computer Science from the University of Crete in 2017 and 2020, respectively. My main research interests fall at the intersection of managed programming languages and runtimes, memory, and storage systems. My work focuses on exploiting emerging non-volatile memories and fast block-addressable storage devices to improve heap efficiency in managed languages for data warehouse workloads, such as big-data analytics frameworks. My recent work resolves the tension between garbage collection and serialization/deserialization by providing a separate scanless managed heap over storage devices. It eliminates both garbage collection and serialization overheads without imposing any language restrictions.
