I'm a second-year Computer Science PhD at The University of Illinois-Urbana Champaign. I currently work with Prof. Tianyin Xu on cloud systems reliability.
I'm interested in the reliability of all kinds of systems:
- Traditional/Cloud-native Distributed systems: TiDB, Cassandra, etc.
- AIOps/Agentic Frameworks & Reliability: LangGraph, AIOpsLab, ITBench, etc.
- Microservice architecture
- and so on...
Generally, I'm mostly interested in these questions, and I plan to use my PhD thesis to answer them:
- Does the system break? (yes, otherwise I'm out of work :))
- Why/How does the system break?
- How can we patch the failures or prevent them?
- How can we build systems that doesn't break as frequent? or potentially, at all?
A short bio can be found here.
