As a doctoral researcher, my focus is on improving Reinforcement Learning & Large Language Models (LLMs) training and inference latency on High-Performance Computing (HPC) clusters & edge devices.
Besides, I find immense joy in pushing my boundaries by tackling complex issues that have the potential to positively impact the public. My fervor converges with enhancing computer systems, networks, databases, and their corresponding security aspects, which allows me to have impacts on computing for both the environment (greener while efficient) and people (faster while reliable). I am also a passionate free software developer, I maintain several open-source projects and contribute to many others.
