About Dr Alexandros Koliousis

Alexandros Koliousis is an Associate Professor in computer science at Northeastern University London and a Senior Research Scientist at the Northeastern’s Institute for Experiential AI (EAI). He works on the design and implementation of scalable AI systems. Currently, Koliousis aims to develop a framework for the verification and testing of AI systems.
Koliousis has worked on high-performance data-parallel multi-GPU processing systems in the areas of deep learning and data stream processing. He has also researched topics including efficient natural language processing in hardware and complex event processing for network and system management.

Before joining Northeastern, Koliousis held an industry research position at the semiconductor company Graphcore and academic positions at the Imperial College London and the University of Glasgow. He earned his doctoral degree in computing science and his Master of Science in advanced computing science from the School of Computing Science at the University of Glasgow.


Alexandros received his PhD (Computing Science, 2010) and MSc (Advanced Computing Science, 2005) degrees from the School of Computing Science at the University of Glasgow.

He received his undergraduate degree (Computer Engineering, 2003) from the Alexander Technological Educational Institute of Thessaloniki, Greece.



Dr Alexandros Koliousis's Research

Alexandros’s research interests lie at the intersection of scalable data systems and deep learning. He has worked on the design and implementation of data-parallel processing systems that best utilise hardware accelerators with applications to deep learning (Crossbow, 2019) and data streaming (Saber, 2016).

He has also worked on complex event processing for home network management; and routing algorithms for wireless sensor networks, among other topics.
