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.

My interests include systems, networking and computer architecture.
For my Ph.D. I am rethinking distributed memory systems in the context of high-end smart datacenter networks (RDMA). I am currently focused on data replication for high performance and safety (i.e., consistency and fault-tolerance).

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