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. Nandita Vijaykumar and Prof. Onur Mutlu (SAFARI research group), and their research groups. 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, computer systems and high-performance computing. My current research focuses on the hardware/software co-design of emerging applications with modern computing systems. In my PhD, I designed intelligent algorithmic techniques and practical hardware mechanisms to accelerate irregular applications, including graph processing, pointer-chasing data structures, in large-scale multicore systems, disaggregated memory systems and processing-in-memory architectures. In my PostDoc, I proposed memory-efficient algorithms, compression engines, and adaptive runtime systems to accelerate machine learning models in GPU systems and processing-in-memory architectures. This year, thanks to my research achievements in the field of machine learning systems, I am honored to be selected as a 2024 MLCommons Rising Star. I have also received a Postdoctoral Research Fellowship from the Vector Institute for AI.
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. I hold a M.Eng. equivalent degree (2011-2016) from ECE NTUA, where I graduated in the top 2% of my class.
I am on the academic job market in the 2024-2025 cycle. Please feel free to reach out for potential opportunities.
