Dr. Hamidreza Khaleghzadeh is a Senior Lecturer in the School of Computing at the University of Portsmouth, UK. He received his PhD in Computer Science from University College Dublin (UCD), Ireland, in 2019, specialising in data-partitioning algorithms for performance and energy optimisation on heterogeneous HPC platforms. Previously, he was a Postdoctoral Researcher at the Heterogeneous Computing Lab (HCL), UCD. His research focuses on heterogeneous high-performance computing, parallel and distributed systems, and energy-efficient (green) computing, particularly on optimisation across CPUs, GPUs, and accelerators. He has contributed to advancing performance and energy-aware computing for large-scale data-parallel and big data applications. His work supports the development of sustainable and green computing systems.
