Dr Hamidreza Khaleghzadeh
Biography
I am a Senior Lecturer in the School of Computing at University of Portsmouth, United Kingdom. Previously, I held the position of Postdoctoral Researcher in Heterogeneous Computing Lab (HCL) at University College Dublin (UCD), and lecturer/MSc supervisor at Dublin Business School (DBS).
I obtained my PhD in Computer Science in 2019 from University College Dublin (UCD), Ireland. My PhD topic is Novel Data-Partitioning Algorithms for Performance and Energy Optimization of Data-Parallel Applications on Modern Heterogeneous HPC Platforms: the PhD focused on data-partitioning techniques addressing performance and energy optimisation of parallel applications executing on multicore CPUs, GPUs, Xeon Phis, FPGAs, etc. I completed my BSc and MSc in Computer Engineering in 2008 and 2011, respectively.
My area of expertise is in the performance and energy optimisation of Heterogeneous High-Performance Computing (HPC) platforms, Energy-Efficient Computing systems and Big Data Applications.
I have several peer-reviewed publications published in world-leading journals such as IEEE Transactions on Parallel and Distributed Systems (IF 2.687), IEEE Access (IF 3.367), Journal of Supercomputing (IF 2.6). You can find my publications on Google Scholar.
I am a member of the European Network for Sustainable Ultrascale Computing (NESUS).
Research interests
My research focuses on the models, algorithms, methods, software tools, systems and development practices that will facilitate performance and energy optimisation on state-of-the-art heterogeneous (HPC) platforms. My area of expertise is in the performance and energy optimisation of Heterogeneous High-Performance Computing (HPC) platforms, and Energy-Efficient Computing Systems. My research goals are to employ my HPC and energy-efficient computing skills to bridge a gap between HPC and other fields such as machine learning, data analytics, and artificial intelligence.
So, my research interests can be itemized as follows:
- Parallel and High-Performance Computing
- Energy-efficient Computing
- Machine Learning and Big Data Applications
Teaching responsibilities
I am currently involved as module coordinator and lecturer in the following units:
- M30248 Parallel Programming
- M33146 Big Data and Machine Learning Applications
- M30249 Scientific Computing and Simulation
- M22508/M24739 Final Year Undergraduate Project (A member of the admin team)
I also supervise Master’s (taught and by research) and Undergraduate students.
