About Me

I am a 5th year PhD candidate in Computer Science, co-advised by Dr. Hank Childs and Dr. Allen D. Malony, at the University of Oregon. Prior to joining the University of Oregon, I received my Bachelors in Computer Science from National University of Computer and Emerging Sciences (FAST-NU) in 2018.

Research Interests

My research interests lie in high-performance computing (HPC), performance analysis, parallel I/O, visualization, and systems for AI/ML. My work focuses on end-to-end analysis, visualization, and optimization of parallel I/O performance in scientific and AI/ML workloads. I have collaborated with several U.S. national laboratories—including Fermilab, Lawrence Livermore, and Lawrence Berkeley—on projects aimed at improving I/O performance in data intensive HPC and AI/ML applications.
