I graduated with a bachelor’s degree from Harbin Institute of Technology (Shenzhen) and am currently a PhD student in School of Data Science at The Chinese University of Hong Kong, Shenzhen (CUHK(SZ)) and fortunate to be advised by Prof. Pinjia He.

My research centers on software reliability, security and observability through innovative testing and monitoring methodologies.

I warmly welcome collaborations and discussions in this domain (DevOps, MLOps, LLMOps, AI4SE, SE4AI).
