About

I am a PhD candidate in the School of Electrical and Computer Engineering (ECE) at the National Technical University of Athens (NTUA). I am working at the Computing Systems Laboratory, and I am also collaborating with the SAFARI research group at ETH Zürich, which is led by Prof. Onur Mutlu.

My research interests lie in the intersection of computer architecture and high-performance computing. My current research focuses in the hardware/software co-design of emerging applications, including graph processing, pointer-chasing data structures, machine learning workloads, and sparse linear algebra, with modern computing paradigms, such as large-scale multicore systems and near-data processing architectures. I am also excited about designing scalable memory hierarchies and efficient hardware support for synchronization and concurrency.

During my PhD studies, I had been receiving a PhD Fellowship (Oct 2017-Mar 2020) from the General Secretariat for Research and Technology (GSRT) and the Hellenic Foundation for Research and Innovation (HFRI). I was fortunate to also be a visiting PhD researcher in the SAFARI research group at ETH Zürich advised by Prof. Onur Mutlu and mentored by Prof. Nandita Vijaykumar. I hold a M.Eng. equivalent degree (2011-2016) from ECE NTUA, graduated in the top 2% of my class.
