I am an assistant professor in the College of Computer and Systems Engineering at Abdullah Al Salem University, Kuwait. I work on operating systems and memory systems: how the system software should place, move and manage memory on machines whose memory is not uniform, from NUMA servers to integrated CPU-GPU chips and processing-in-memory hardware. I also work on computer systems security, with a particular interest in Linux kernel exploitation.

My PhD, at the University of British Columbia, was on understanding and mitigating memory-access challenges in computing systems; my MSc at Simon Fraser University on resource-contention management in the Linux kernel for multicore NUMA systems.

My papers follow that thread from NUMA servers to newer hardware: NUMA-aware contention management on multicore systems (USENIX ATC 2011); Carrefour, a holistic approach to memory placement on NUMA systems (ASPLOS 2013), and the challenges of memory management on modern NUMA systems (Communications of the ACM, 2015); memory management on integrated CPU-GPU systems (ISMM 2017) and whether garbage collection is worth accelerating on integrated GPUs (2020); and a case study of processing-in-memory in off-the-shelf systems (USENIX ATC 2021). Before that, I worked on confirming connectivity in interworked broadcast and mobile networks (IEEE Network, 2007).

Lately: systems security in general, and Linux kernel security in particular; unified CPU-GPU memory performance across edge, consumer and datacenter platforms (Electronics, 2026); and augmenting operating-system randomness with publicly observable data sources (Cryptography, 2026).
