About Me
I am completing my Ph.D. by May 2021, and I am actively looking for jobs (both long-term internship and full-time job).
I am a Computer Science PhD candidate in EECS at University of California, Merced, where I am a member of Parallel Architecture, System, and Algorithm Lab (PASA)and advised by Dr. Dong Li. Before coming to UC Merced, I earned my master degree in Computer Science and Engineering from Michigan State University. Since January 2020, I serve as the graduate student representative at EECS, UC Merced.
Research Interests
My research area is high performance computing with a focus on hardware heterogeneity. I design high performance computer systems for large-scale parallel systems with memory heterogeneity. My recent work focuses on designing system support for persistent memory-based big memory platforms.
- Computer system
- Memory and storage system
- High performance computing
- Parallel programming model
- Runtime scheduling
- System resilience and reliability
- Data processing framework (OLTP/OLAP/HTAP/Key-value store)
