Arthur P. Feeney

I am a PhD student in the department of Electrical Engineering and Computer Science at the University of California Irvine. I work at the intersection of high‑performance computing and machine learning, with a focus on building scalable systems for scientific workloads.

My research interests include GPU programming, performance engineering, and machine learning for science. I enjoy designing algorithms and software that make large‑scale problems and data analysis faster, more efficient, and easier to use.
