Yen-Hsiang Chang

My research interests lie in the general area of high-performance computing, particularly in parallel programming and algorithms, with the focus on graph algorithms and applied numerical linear algebra.

I am a third-year EECS Ph.D. student at UC Berkeley, advisded by Prof. Jim Demmel. During my first two years, I was also co-advised by Dr. Aydın Buluç. I am associated with Sparsitute, PASSION Lab and BeBOP.

I received my B.S. in Computer Engineering from UIUC in 2022, with Highest Honors and with a minor in Mathematics. I have had the privilege to work with Prof. Wen-mei Hwu, Prof. Rakesh Nagi, and Prof. Jinjun Xiong at Illinois.

If you'd like to learn more about me, please see my CV or contact me via email.
