      Research Interests

      I am a Professor in High Performance and Distributed Computing and the Head of the School of Electronics, Electrical Engineering and Computer Science, at Queen's University of Belfast. I am also acting as Director of the ECIT Centre for Data Science and Scalable Computing. My research expertise is in system software, with particular emphasis on performance, power and reliability aspects of servers and distributed systems. I am the recipient of a Royal Society Wolfson Research Merit Award, the NSF CAREER Award, the DOE CAREER Award, the IBM Faculty Award, the SFI-DEL Investigator Award and Best Paper Awards from some of the premier IEEE and ACM conferences in my area, including SC, PPoPP, and IPDPS. I have mentored 14 PhD students and 14 post-doctoral research fellows over my career. We jointly produced over 190 top-tier papers (h-index=29), with extensive funding (£11.1m in a Principal Investigator and £43.4m in a CoInvestigator role) awarded competitively by the NSF, DOE, EPSRC, SFI, NI DfE, Royal Academy of Engineering, Royal Society, the European Commission, IBM, SAP and Intel. I have taught modules in computer organisation, computer architecture, parallel programming, operating systems and embedded systems and I am always looking forward to getting back to undergraduate teaching. I am a  Fellow of the Institute of Engineering Technology, Fellow of the British Computer Society, Senior Member of the IEEE and Senior Member of the ACM. I earned PhD (2000), MSc (1997) and BEng (1996) degrees in Computer Engineering and Informatics from the University of Patras.
