About Me

Technology is my passion. I am always excited to amplify my knowledge in diverse subjects like science, biology, neurology, math and technical things. I chose to study Computer Science, at the University of Crete. In parallel with my Bachelor studies, I was also working as a Research Assistant in the Computer Architecture and VLSI Systems Laboratory. Currently I am pursuing my PhD in Pervasive Parallelism at the University of Edinburgh.

I am always excited to work on:
- Software-Hardware co-design
- Idea Cross-pollination: systems, databases, architecture, networking
- Intersection of Theory & Practice: revisit first principles to build next generation systems.

For my Ph.D. I rethink data replication in the modern datacenter. This involves designing systems and algorithms to resolve challenges in performance, consistency, load-balance, fault-tolerance and transactions. Mostly storage solutions in distributed environments which tend to include emerging networking (e.g., smart RDMA NICs) and/or specialized compute (e.g., FPGAs).

In my own time, I enjoy swimming, meditating, listening to audiobooks and music.
