Jinghan Sun |

I am a final-year CS Ph.D. student at the University of Illinois at Urbana-Champaign, advised by Prof. Marc Snir and Prof. Jian Huang. My research interests are at the intersection of machine learning (ML) and systems, with a particular focus on building efficient and reliable storage systems using machine learning. I work across the entire storage stack, from storage hardware development (e.g., solid-state drives) to system software and cloud storage platforms.

I am on the academic job market!

Miscellaneous

I enjoy playing soccer in my spare time. I also love classical music. My favorite composers are J.S. Bach and Frederic Chopin, and I can play some of their shorter piano pieces.
