About Me
I am a tenure-track Associate Professor at Nanjing University. I received my Ph.D. degree from Tsinghua University in 2023 (Advisor: Prof. Jiwu Shu), and Bachelor's degree from Huazhong University of Science and Technology in 2018. From 2023 to 2025, I worked as a Postdoctoral Researcher at Tsinghua University.
Prospective students: If you're passionate about system research and interested in working with me, please feel free to reach out via email.
Research
My research focuses on computer systems, particularly storage/memory systems and networked systems.
Below are several recent research projects:
-
Lifting network-level knowledge to storage software
- Leveraging NIC hardware ACKs for fast commit (NSDI'25)
-
Distributed protocols with network supports
- In-network cache coherence (FAST'21)
- Network primitives for replication (OSDI'23)
-
Indexes for different network links
- NUMA-aware index (OSDI'21)
- Index on disaggregated memory (EuroSys'25, SIGMOD'22)
-
Memory management
- SSD-extended remote memory (FAST'24)
- Protective remote memory (FAST'23)
- Memory compaction (USENIX ATC'22)
-
Concurrency
- Distributed Locks (FAST'25, FAST'23)
- Transactions (USENIX ATC'22, VLDB'22, DAC'20)
