✨ Hi, I’m Ning Li. I'm lucky to have met you. I'm working on my PhD at East China Normal University (ECNU).

😺 My research interest is software engineering, especially performance anomaly detection, diagnosis and repair. In addition, there are some other points of interest such as synchronous performance optimisation, memory performance evaluation, and microarchitecture performance analysis.
