I am a Postdoctoral Researcher at the University of Toronto working with Prof. Gennady Pekhimenko and the EcoSystem research group. I am also working with Prof. Andreas Moshovos, Prof. Onur Mutlu and his research group, the SAFARI research group. I received my Ph.D. in October 2022 from School of Electrical and Computer Engineering (ECE) at the National Technical University of Athens (NTUA), where I was a member of the Computing Systems Laboratory and I was advised by Prof. Georgios Goumas, Prof. Nectarios Koziris and 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, disaggregated memory 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 award (Sep 2021-Oct 2022) from the Foundation for Education and European Culture, and 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, where I graduated in the top 2% of my class.
I am looking for strong Master’s and senior undergrads to collaborate. If you are interested in doing research in the fields of machine learning, computer architecture and computer systems, feel free to drop me a message.
