Welcome to my personal web page!
I’m a researcher in Computer Science with 15+ years of experience in engineering high-performance systems. I’m also a tinkerer with a curious mind, an entrepreneurial spirit and a passion for technology and science. I care a lot about the design of a sustainable environment for a future society with abundance, more freedom and happiness.
My contributions in the area of computer systems include 25+ peer-reviewed publications in conferences, journals and books, as well as contributions to several research projects, conferences and dozens of paper reviews for major conferences and journals.
Since early 2012, I’m a Software Architect and Researcher in the Emerging Technologies Group of OnApp, a UK-based company developing a Cloud IaaS platform with an Integrated distributed Storage system.
My work involves engineering storage software components in the Linux kernel, as well as buidling and testing user-space distributed I/O stacks (block and file layers). Additionally, I’m a researcher engaged in several R&D projects, such as the Euroserver FP7-funded R&D project for emerging, power-efficient micro-server architectures, focusing more specifically on the topics of (i) scalable network and storage I/O, and (ii) energy-driven resource management in cloud architectures.
My recent research activities are focused on performance, scalability, reliability and management issues in direct-attached and distributed storage systems. The topic of my Ph.D. thesis is “Extensible Networked-Storage Virtualization with Metadata Management at the Block Level”. Past research experience in the areas of Grid computing, Distributed systems, Security, Web Caching and Network RAM.

Since last month (Feb. 2012), I’ve started working for OnApp, a UK-based company developing cloud software for hosts.
My role as a Core Engineer in the Storage Platform Group involves architecting and engineering storage software components in the Linux kernel. Hopefully some of these components will be released soon, along with our product releases. For the moment stay tuned for more news & releases soon…
On July 1st, 2011 I left my position as Collaborating Researcher at FORTH-ICS to start working independently on new projects, solving new problems and learning new things. I’ll be posting updates about my work, projects and ideas in the next few months. Expecting exciting times ahead…
The NGPaaS project aims to implement the next-generation Platform-as-a-Service.
The ACTiCLOUD project aims to implement an efficient and active rack-scale Cloud platform.
Modified Xen Blkback driver providing Multiple private queues for Xen v3 and v4 for the OnApp Integrated Storage platform.
Design and implementation of a fault-tolerant syncronous mirroring layer (kernel module) for the Linux device mapper.
Modified & extended kernel driver for Network Block Devices (nbd) for the OnApp Integrated Storage platform.
Implementation of a reverse striping module for the OnApp Integrated Storage platform.
The Superfludity project aims to implement a highly-fluid universal cloud services platform.
The SHARCS project aims to design and implement a highly-secure platform.
The Euroserver project aims to implement a highly-efficient low-power microserver using ARM SoCs.
The Trilogy 2 project aims to design and implement an efficient cloud architecture that scales across cloud service providers.
